Talk Title
Liquid Biofuel Property Predictions using Molecular Dynamics Simulation

Talk Abstract

Biofuels represent the only long-term alternative to fossil fuels for energy utilisation such as transport applications, where biodiesel and bioethanol are particularly attractive. Liquid biofuels and biofuel blends are drawing increasing attention. Accurate predictions of fuel physicochemical properties of these new fuels are crucial to their utilisation, but yet to be fully achieved. The usage of biofuels will lead to uncertainties and the technical applicability of blended plant based biofuel/conventional fuel exhibit major challenges both fundamentally and practically. For instance, optimisation of the fuel blends requires rigorous research to advance the current knowledge. Combustion of unexplored thermodynamic environments where new physical and chemical fuel properties result in complex interactions with respect to fuel variability is not well understood. This study is associated to the development and assessment of fuel property predictions, which also includes predictions of the oxidation process and species formation of combustion of biofuels and biofuel blends.

Molecular dynamics simulations are used to predict the physicochemical properties of biofuels and biofuel blends and their combustion. Fuel property results will be provided for different fuel compositions of blended fuel and for different operating conditions relevant to practical applications. Evaluation of physicochemical properties of liquid biofuel combustion at varied operating conditions will be provided.

The research will help achieving the greenhouse gas emission reduction targets. It will also potentially increase the contribution of renewable biofuels to the energy supply mix, and help the industries to establish their products into larger and more advanced technologies.

Short Biography

Professor Jiang currently chairs the Division of Mechanical Engineering, Robotics & Design within the School of Engineering and Materials Science at Queen Mary University of London (QMUL). He re-joined QMUL in March 2017 after holding the post of Chair in Energy Use and Transport at Lancaster University for more than seven years, following previous research experience developed in Brunel University, QMUL, Seoul National University and University of Science & Technology of China. He has a wide-ranged successful experience in numerical studies of fluid flow, heat transfer and combustion and has been working on various research topics related to turbulence, combustion and aeroacoustics. His research has been mainly focused on advanced simulation and modelling of flow and combustion problems using direct numerical simulation (DNS) and large eddy simulation (LES), including DNS of reacting flows and gas-liquid two-phase jet flows and LES of fuel injection and spray combustion. His group has also carried out numerical simulation of CO2 migration in geological formation for greenhouse gas (GHG) emission mitigation. In his research field of Energy & Flow Physics, he has an international profile with more than 100 peer-reviewed publications, including important review journals such as Progress in Energy and Combustion Science (Jiang et al. 2010, Vol. 36, pp. 131-167; Jiang et al. 2018, Vol. 66, pp. 176-199). In addition, he has authored a Taylor & Francis book “Numerical Techniques for Direct and Large-Eddy Simulations” (2009). Over the last fifteen years, his research has been supported by EPSRC, EU H2020, Innovate UK and the industry with a number of funded projects. The expertise of Prof Jiang is primarily in sustainable and cleaner energy utilisation, which includes but not limited to the applications of high-fidelity modelling and simulation to the following research areas: (1) combustion utilisation of alternative and renewable fuels including chemical kinetics studies, (2) greenhouse gas mitigation technologies including combustion mitigation of low-concentration methane; (3) flow in porous media and geological carbon storage, and (4) battery thermal management and thermal management in computer systems.
