HPC   Applications Specialist, University of Nebraska Lincoln, USA

High-performance thermal   interface materials (TIMs) have attracted persistent attention for the design   and development of miniaturized nanoelectronic devices; however, a large   number of potential new materials exist to form these heterostructures and   the explorations of their thermal properties are time consuming and   expensive. In this work, we train several supervised machine learning (ML)   and artificial neural network (ANN) models to predict the interfacial thermal   resistance (R) between graphene and hexagonal boron–nitride (hBN) with only   the knowledge of the system temperature, coupling strength between two   layers, and in-plane tensile strains. The training data were obtained by   high-throughput computations (HTCs) of R using classical molecular dynamics   (MD) simulations. Four different ML models, i.e., linear regression,   polynomial regression, decision tree and random forest, are explored. A pair   of one dense layer ANNs and another pair of two dense layer deep neural   networks (DNNs) are also investigated. It is reported that the DNN models   provide better R prediction results compared to the ML models. The thermal   property predictions using HTC and ML/ANN models are applicable to a wide   range of materials and open up new perspectives in the explorations of TIMs.

Microscale   Studies on Hydrodynamics and Mass Transfer of Dense Carbon Dioxide Segments   in Water

Research   Fellow, Harvard Medical School, Massachusetts General Hospital, USA

Microfluidic technologies are   powerful tools in assisting the probes into complicated physical-chemical   interactions of multiphase fluids in microscale geometries. Among such   studies, carbon dioxide (CO2) has drawn increasing attention because of their   environmental impacts such as greenhouse gas effects. However, dense CO2   including liquid and supercritical states as results of the storage   circumstance in deep geoformations (depth > 800m) are rarely investigated   mainly due to great technical difficulties in working with extreme pressures   (~10s bar) and elevated temperatures (> 31°C). My PhD thesis research   presents some first studies of the hydrodynamics and mass transfer of dense   CO2 segments in microchannels. First, an experimental system dedicated to two   phase microfluidic studies, especially for those related to extreme   pressure/temperature conditions will be introduced. This system is one of a   few in the world that enables quantitative studies of two- and multi-phase   microflows. Second, an experimental study of liquid CO2/deionized (DI) water   two phase flows in a micro T-junction will be presented, in which drop flow   and co-flow are identified. Focusing on the drop flow, mass transfer   mechanisms involving CO2 hydration, diffusion and advection and their effects   in CO2 molecules transport are considered and discussed. Third, experimental   investigations of the hydrodynamics and mass transfer of liquid CO2 and scCO2   drops traveling simultaneously with water in a long straight microchannel   (15mm long) will be reported. Drop size and speed at specified positions of   the channel are quantified. We proposed and developed a mathematical model to   calculate the mass transfer coefficient based on drop length reductions and   flowing time in the channel. Results indicate that surface-volume ratio and   drop flow time are two main factors in controlling the hydrodynamic shrinkage   of the liquid CO2 and scCO2 drops. Last, a numerical study will be presented   shedding light on the hydrodynamics of single liquid CO2 drop and single   scCO2 drop when they flow simultaneously with water as a carrier phase in a   straight microchannel. Three liquid CO2 and three scCO2 cases are studied.   The computed drop is in a capsule-like shape encapsulated by thin water films   whose thickness agrees very well with experimental results in literature. The   flow domain within CO2 drops are generally composed of a few vortex regions   indicating the hydrodynamic scenario inside the drop. Formations of these   vortexes are attributed to the shear stress nearby the interface.

Dr. Ning Qin is currently a   postdoctoral research fellow at the Wellman Center for Photomedicine at   Massachusetts General Hospital (MGH) and Harvard Medical School (HMS). His   research work at MGH and HMS is very interdisciplinary that spans microfluidics   and biomedical optics and aims to the development of advanced technologies   and instrument for rapid, effective, and point-of-care blood coagulation   analyses. Dr. Qin’s research interests lie in multiple areas such as   microfluidics, lab-on-a-chip technologies, droplets/bubbles, heat and mass   transfer, fluid mechanics, and carbon capture and storage (CCS). He received   a bachelor’s degree in thermal engineering from Shandong University in 2009   and a master’s degree in refrigeration and cryogenics engineering from the   Technical Institute of Physics and Chemistry, Chinses Academy of Sciences in   2012. He graduated and obtained his PhD degree in mechanical engineering from   the University of Waterloo, Canada in 2017. During his PhD, he was a   part-time research engineer at Genemis Laboratories Inc. based at Cambridge,   Ontario, Canada and was a R&D consultant at QuantWave Technologies Inc.   at Kitchener, Ontario. He was also a visiting scholar at the Institute for   Bioprocessing and Analytical Measurement Techniques (iba) e.V., Heilbad   Heiligenstadt, Germany in 2016. Dr. Qin is now a member of American Physical   Society (APS) and a member of Canadian Society of Mechanical Engineering. He   is a reviewer of multiple academic journals such as Physical Review E, Lab on   a Chip, Energy & Fuels, Applied Energy, and Chemical Engineering Science.

The   Simple and Complicated Heat and Mass Management of PEM Fuel Cells and Water   Electrolysers

高鑫

丹麦奥尔堡大学，博士后

Postdoc,   Aalborg University, Denmark

This presentation gives a brief   review of all my research work in different projects at Aalborg University,   Denmark. Most of these projects are funded by Danish Ministry of Education   (UVM) and Danish Energy Agency (ENS). Researches are mainly done on the heat   and mass management optimization of these systems, 1) a methanol-fueled PBI   membrane high temperature fuel cell system from SerEnergy A/S, 2) two   generations of air-cooled FCgen®-H2PM LT-PEM systems from Ballard Europe A/S,   3) a liquid-cooled LT-PEM system, Ballard FCveloCity® for a forklift, 4) a   PEM water electrolysis from EWII A/S.

The complication of their heat   and mass management is from the fact that they include vast phenomena, like   electrochemical reactions, heat and mass transfer from µm to mm scale,   multi-phase phase flow, and material property/contact-surface imperfectness,   etc. All of these cause it expensive to measure accurately and cumbersome to   simulate. Some phenomena themselves alone are under intensive research and   still lack of thorough understanding. The simplicity is in the sense that a   lot of phenomena are actually linked to and determined by the well defined   models of heat and mass transfer in almost every textbook. However, simple   does not mean obvious. Simple but tricky may be the most apt words. Join this   presentation, let me show you some of my simple discoveries that may refresh   your believes.

Xin Gao was born in Shandong   Province, China. He got his B.Eng. in Thermal Power Engineering and   Automation from Nanjing University of Science and Technology in 2000. He   received M.Sc. Eng. in Automotive Power Machinery and Engineering from School   of Automotive Studies, Tongji University in 2009. In 2014 he was honored   Ph.D. in Energy Technology at Aalborg University and continued working in the   same group as a postdoctoral researcher until now. His research interests   cover heat and mass management optimization, multi-phase flow,   thermodynamics, fluid-dynamics and their numerical simulations inside   PEM/PBI-membrane fuel cells and water electrolysis. Besides, he has also   worked on thermoelectric (Seebeck) devices and sought combining them with   fuel cell systems for mutual benefits in steady-state and transient   situations. During his PhD and postdoc, he has 9 published in journals, like   Nano Research, Journal of Power Sources, and International Journal of   Hydrogen Energy, among 20 in total and 5 more being worked on. At the same   time, he has been teaching the course Heat Transfer and supervising students’   semester projects regularly. Furthermore, he serves the research community by   attending international conferences for 10 times and as reviewer for journals   and conferences, like Applied Energy, International Journal of Hydrogen   Energy, Applied Thermal Engineering for more than 30 times. He also visited   Iowa State University as a visiting scholar and Tsinghua University as a   project specialist in 2016.

Direct   Numerical Simulation of Lean Premixed Turbulent Flames at High Karlovitz   Numbers under Elevated Pressures

王旭江

英国伦敦大学学院，博士

University   College London, UK

With growing concern about global   climate change and increasingly stringent regulations on pollutants   emissions, lean premixed combustion has had wide-ranging applications in   industrial devices, e.g. stationary gas turbines. The turbulent flames in gas   turbines are characterised by high-intensity turbulence and pressure. Under   these critical conditions, flame structures and chemical processes will be   dramatically modified. Therefore, it is vital to have a good understanding of   fundamental characteristics of lean premixed combustion under critical   conditions, which will promote the development of combustion devices and   assist to validate turbulent combustion models. However, it is difficult and   expensive to conduct experiments under high pressures. With the availability   of increasingly powerful supercomputers, direct numerical simulation (DNS) of   turbulent reacting flows has become feasible and affordable. The present   study focuses on DNS of lean premixed H2/air flames under varying Karlovitz   numbers, pressures and equivalence ratios. The effects of dominating   parameters on turbulent flame structures and chemical pathways are analysed   qualitatively and statistically.
