Multiphase & Multiphysics Flows
Coupled heat, mass and phase transport — from rarefied gas to particle-laden turbulence
Overview
This research programme spans a broad range of multiphysics problems: buoyancy-driven convection (Rayleigh–Bénard and salt-finger regimes), particle-laden turbulence, and rarefied gas dynamics using Direct Simulation Monte Carlo (DSMC). A common thread is coupling between flow and a transported scalar — temperature, concentration, or phase — with implications for geophysical, atmospheric, and engineering systems.
