Computation of Fluid Dynamics
- Department of Process Engineering
Lectures are oriented upon fundamentals of CFD and first of all to control volume methods (application using Fluent)
Fundamental mathematics (derivatives, integrals, vectors)
- Syllabus of lectures:
Aerodynamics. Drag coefficient.
hydraulic systems (fuel pumps, injectors), spray and droplet formation, new application magnetorheological and electrorheological fluids / suspension, brakes.
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.
