Introduction to Technical Thermos-Mechanics of Compressible Fluids
(1) Introduction to the Thermodynamics of a compressible fluid. (2) A short review of the Thermodynamics: Basic expressions and basic relations, first and second law of thermodynamics. State and process variables, closed and open systems, work of expansion (and compression), shaft work and technical work, specific heat, dissipation, enthalpy, entropy. (3) Thermomechanics of a compressible fluid: The perfect-gas relationship, speed of sound waves, Mach number, isentropic flow, shock waves, Fanno and Rayleigh line, adiabatic flow with friction in conduits, frictionless flow with heat transfer, steady isothermal flow, isothermal flow in long pipes, subsonic and supersonic flow in pipes. (4) Non-deformable bodies in a flow of compressible fluids. Three important speed ranges: high speed subsonic, trans-sonic and supersonic. Approaching the speed of sound, the transsonic flight, normal and oblique shock waves, the effects of shockwaves. Movement of soundlines and shockwaves on the surface of an airofoil. Supersonic flow round a corner (sharp edged or rounded). The centre of pressure position.
