Goal

Students should get acquainted with possibilities and gain knowledge of the theoretical basis of the finite volume method. They should to educate for using numerical methods for solving problems in the area of fluid mechanics and area of heat and mass transfer. Regardless of the complexity of the problem - geometry and boundary conditions, the acquired knowledge will enable them to calculate velocity field, temperature field and field of concentration of some substance in fluids or/and in solids in which these processes are occurred .

Outcome

After the course and after independently performed numerical examples, students would have fundamentals knowledge of the theoretical of numerical methods used to solve problems in the field of fluid mechanics and field of the heat and mass transfer. Also, they would be able to make predictions, i.e. computer simulations of fluid flow and transport of heat and mass by using commercial CFD program PHOENICS 3.1.
