Thermodynamics, fluid dynamics
Objectives
Fluid dynamics is based on a number of basic laws of thermodynamics and fluid dynamics, consisting of: conservation of energy, momentum and mass. Using these laws it is possible to determine the efficiency of thermal machines. The study of fluid/gas flow gives the opportunity to understand and calculate practical applications using analytical, experimental and numerical methods. Hydraulic losses in pipe systems, external flow around airplane wings, cars, etc… are typical applications.
Topics
Thermodynamics:
Conservation law of energy for open and closed systems.
The second law of thermodynamics ( entropy).
Heat transfer ( conduction, convection and emission).
Fluid dynamics:
Introduction of the basic concepts and typical flow phenomena using practical applications.
Introduction of the basic laws of fluid dynamics. Starting from the given Reynolds-averaged Navier-Stokes equations, simplified models are derived and their applicability is illustrated.
Analytical and semi-empirical models are studied and exercised.
Introduction of computational fluid dynamics (CFD) within CAE environment. The numerical simulation process of fluid flow and heat transfer are explained, demonstrated and exercised.
Introduction of experimental methods including visualisation and measurement techniques.
