Objectives
Part I Turbines : Principles of steam-, gas-, wind and water turbines used in Electrical Power Plants. Elementary analyse of different types of machines. Basics of Jet engine.
Part II Numerical Fluid Dynamics : to teach the student the basics in Numerical Fluid Dynamics, numerical Flow Simulation or Computational Fluid Dynamics, CFD. The scientific background of CFD, including the physical, mathematical and numerical modelling disciplines will be introduced. During the computer assignments the basic steps of a CFD calculation will be teached, where classical applications are simulated, evaluated and validated. As a final goal the student will apply his knowledge and first experiences in a CFD project.
Topics
Part I Turbines : Fluid flow in nozzles and difusors. Steam turbine : basic principles impuls and reaction turbine. Laval, Curtis an Rateau turbine. Gas turbine. Basics of jet engine. Hydraulic turbines : Pelton, Francis and Kaplan turbine. Wind turbine.
Part II Numerical Fluid Dynamics : an overview of state- of the art CFD technology and applications will be discused. Starting from the physical modelling and conservation laws, the Navier -Stokes equations will be derived and a hierarchy of mathematical models will be discussed : DNS, VLES, RANS, Euler,... A survey of numerical models applied in CFD will be presented ( including finite differences FD, finite elements FE and finit volumes FV ) The basic fundamentals of the FV method will be derived including space and time discretisation algorithms, applied tothe 1D convection-diffusion equation. The aspect of accuracy, stability and convergence are introduced. Meshing techniques for CFD applications will be presented. During the computer assignments, the basic CFD concepts and steps are teached, for classical applications. Special attention will be paid to the interpretation and validation of the numerical results in comparison with experimental data and available theoretical models.
