Synopsis:

Lectures are oriented upon fundamentals of CFD and first of all to control volume methods (application using Fluent)

Requirements:

Fundamental mathematics (derivatives, integrals, vectors)

Syllabus of lectures:

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.

5. Balancing (mass, momentum, energy). Fluid element and fluid particle. Transport equations.

6. Navier Stokes equations. Turbulence. Transition laminar-turbulent. RANS models: gradient diffusion (Boussinesque). Prandtl, Spalart Alamaras, k-epsilon, RNG, RSM. LES, DNS.

7. Navier Stokes equations solvers. Problems: checkerboard pattern. Control volume methods: SIMPLE, and related techniques for solution of pressure linked equations. Approximation of convective terms (upwind, QUICK). Techniques implemented in Fluent.

8. Applications: Combustion (PDF models), multiphase flows.

Syllabus of tutorials:

Fluent tutorials

Study Objective:

Students should be able to read and understand software manuals and papers concerning CFD. Some basic skills - Fluent.
