Personal statement

Yonghao Zhang is Weir Professor of Thermodynamics and Fluid Mechanics and Director of James Weir Fluids Laboratory ( His ambition is to lead JWFL to advance our understanding of fundamental flow physics and chemistry in micro/nano systems, with the aim of utilising these research advances to develop new technologies with capabilities beyond any currently conceived.

His expertise is in the fluid dynamics of rarefied flows, which presents an important technological challenge, with long-term research and industrial implications. His group is among the first to develop lattice Boltzmann (LB) methods for simulating rarefied flows. In particular, they were the first to prove that high-order LB models can be reduced to the linearised BGK equation, giving confidence that LB models can be applied to highly rarefied gas dynamics. His group also developed a fast spectral method for solving the Boltzmann equation, considering different molecular potential models. His other research activities centre on complex flow physics, including multiphase flows, droplet technologies and granular flows. His research has been funded by the EPSRC, EU FP7, STFC, Royal Society of Edinburgh, and the Leverhulme Trust. 


Has expertise in:

    My research has mainly been on understanding multi-scale and multi-physical flow physics through theoretical, computational and experimental studies. My group has developed a suite of computational models for gas non-equilibrium flows and multiphase flows, especially at the micro/nano scales. These models can be exploited for both fundamental research and engineering design simulations. We have recently been applying our models for pore scale study of unconventional gas flows in ultra-tight porous media, multiphase flows in porous media, and droplet dynamics in microfluidic channels. While we continue our effort to improve our models, we expand our work to erosion and corrosion of oil pipelines, fluids/surface interactions, and vacuum technologies.
