Abstract. Multiphase flow techniques have a broad range of applications in the fields of biomedicine, chemical engineering, energy and environment. Currently, multiphase flows have not been well understood due to their underlying complexity, which greatly hinders the development and application of multiphase flow techniques. The lattice Boltzmann method is an effective tool for modelling and simulation of multiphase flows, which not only help to gain a deep understanding of multiphase flow mechanisms, but also facilitate design and optimization of multiphase flow devices. In this talk, I will first briefly introduce the research background and significance of multiphase flows, and then describe the color-gradient lattice Boltzmann model and how to simulate the thermocapillary flows and surfactant dynamics in the framework of color-gradient model, in which we will emphasize the challenges of modeling and the implementations of the wetting boundary conditions. Subsequently, we will report the influence of the non-Newtonian rheology on the droplet dynamical behavior. Finally, we will present some interesting results regarding the multiphase displacement in porous media, which is linked to the application of CO2 injection and storage.
Bio. Prof. Haihu Liu obtained his BEng and MEng degrees from Xi’an Jiaotong University in July 2004 and July 2007 respectively, and obtained his PhD degree from the University of Strathclyde in January 2011. After completing his PhD, he went to Civil & Environmental Engineering, University of Illinois at Urbana-Champaign where he worked as a Postdoctoral Research Associate for 2.5 years. Then he returned to Strathclyde and worked as a lecturer for one year in the Department of Mechanical & Aerospace Engineering. Currently, he is a full professor in the School of Energy and Power Engineering, Xi’an Jiaotong University, China. His research interests include multiphase flows and heat transfer, droplet-based microfluidics, porous media flows, and multi-physics modelling & simulations.
