Abstract
A future issue of CFD studies applied to the simulation of flows with additional complex physics is briefly addressed. We name this field Multi-physics CFD. A number of unresolved multi-physics problems have been founded in industrial problems, e.g. condensation, cavitation, erosion, and icing in turbomachineiy. Current status of two in-house codes developed by our group: Numerical Turbine(NT) and Supercritical-fluids Simulator(SFS) are briefly introduced to explain how multi-physics CFD can solve such complex flow problems in industrial applications.
