Computer Modelling II
FSI-IPMAcad. year: 2020/2021
The course consists of with theoretical and practical parts. The following topics are dealt with in the theoretical part: Modelling of turbulence. Time-averaged fluid flow. Turbulent diffusivity (viscosity & thermal conductivity), appropriate models. Advanced turbulence models. Two-phase flow modelling using the PSICT-method. Modelling of thermal & solar radiation. The following topics are dealt with in the practical part:: Solution of complex fluid flow & heat transfer problems using the Star-CD CFD-code (3-D problems, thermal & solar radiation, 2-phase flow, combustion).
