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
Acquiring the knowledge of advanced turbulent flow modeling (both theoretically and in practice) to solve the problems contained within PhD thesis topic.
Fluid mechanics, differential and integral calculus, work with PC, knowledge of work in CFD environment is advantage
