Course detail

Computational Modeling of the Turbulent Flow

FSI-9VMTAcad. year: 2020/2021

Course is aimed on theory and practice of turbulent flow simulations. More advanced topics (in relation to currently solved problematics within PhD thesis) are discussed after a short intro to finite volume method and turbulence modeling: multiphase flow simulations (open channel flows, cavitation, solid particles, bubbles), flow in rotating frame of reference, hybrid turbulence modeling and large eddy simulation.

Learning outcomes of the course unit
