Background

Liang Yang is interested in numerical methods for solving multiphysics, multiscale problems, with the application to Marine Renewables. He received his PhD in Computational Mechanics in Swansea University. He holds dual MSc in Computational Mechanics from Swansea University and Universitat Politècnica de Catalunya. He is a visiting scholar in the dep. of Earth Science and Engineering, Imperial College London. Research areas includes:

  • Offshore energy device: multibody dynamics, wave-structure interaction
  • Imaged based modelling: massively parallel fluid/solids simulation with CT-scan
  • Multi-physics coupling: Radiation-thermal-fluid transient analysis 
  • Boiling in porous media: mixture fluid model for heat transfer and phase change
  • Turbulent flow and aeroacoustics: finite element solver and high performance computing
