Summary

The course deals with physical significance of turbulence, mathematical models of laminar and turbulent flow with heat transfer, generally compressible gas flow. Software package ANSYS-FLUENT is applied as a tool for the solution of the fluid flow uses the finite volume method. Mathematical model is defined by system of partial differential equations and boundary and initial conditions considering excerpt common fluid boundary condition various temperature boundary conditions on walls, heat transfer and radiation conditions, species conditions. In detail classical turbulence models are defined. Theory is applied in the solution of engineering fluid flow problems, e.g. flow around obstacles, flow with Archimedes forces, natural convection, heat transfer.
