The course deals with physical significance of turbulence, mathematical models
of laminar and turbulent flow with heat transfer, compressible and
incompressible flow. Software package FLUENT is applied as a tool for the
solution of the fluid flow, using the finite volume method. System of partial
differential equations is solved numerically with defined boundary and initial
conditions. Boundary conditions can be defined as inlet and outlet conditions,
symmetry, periodic conditions, various temperature boundary conditions on
walls are applied. Solution procedure and the definition of solution
parameters is explained. In details the theory of turbulence modeling is
provided, classical k-eps model and further RNG k-eps model (renormalization
group), RSM model (model of Reynolds stress) and explained. Theory is applied
in the solution of engineering fluid flow problems, e.g. flow around
obstacles, flow with Archimedes forces, natural convection, transport of
species, heat transfer.
