Students will learn the physical meaning of turbulence in the flow of real fluids in the general three-dimensional geometry. In detail, they will introduction with the design and creation of computational geometry and network in program DesignModeler and ANSYS Meshing in system ANSYS. Using numerical simulations they will learn how to design and define a mathematical model for solving multiphase flow, flow of species with chemical reactions including the transfer of heat, radiation and time-dependent problems. Furthermore, they encounter with problems of the flow of solid particles in the form of a discrete phase and solution to the problems of heat exchanger.

Lectures

Tutorials

In the course of 3D flow, the students are detailed introduced with the basic terms from the modeling of the fluid flow and mixtures of materials, including the consideration of chemical reactions, heat transfer, radiation, as well as the issue of the flow of particulate matter (solid, liquid, gas) in the form of discrete phases.
