Fundamental mathematics (derivatives, integrals, vectors)

Osnova přednášek:

1. Applications

Aerodynamics. Drag coefficient.

hydraulic systems (fuel pumps, injectors), spray and droplet formation, new application magnetorheological and electrorheological fluids / suspension, brakes.

Turbomachinery.

Chemical engineering reactors, combustion.

2.Implementation CFD in standard software packages Fluent Ansys Gambit.

Problem classification: compressible/incompressible. Types of PDE (hyperbolic, eliptic, parabolic) - examples.

3.Weighted residual Methods (steady state methods, transport equations). Finite differences, finite element, control volume and meshless methods.

4. Mathematical and physical requirements of good numerical methods: stability, boundedness, transportiveness. Order of accuracy. Stability analysis of selected schemes.
