ObjectivesOn completion of this module, students will have extended the foundation thermodynamics and fluid mechanics, developed in earlier years, to cover more advanced concepts and applications. Students will be able to investigate the effects of the major operating parameters controlling the performances of various energy-converting engines that include all of the principal, combustion powered, gas and steam power-plants in common use. Also students will be able to analyse refrigeration and vapour compression systems. Fluid mechanics will be extended to include high speed fluid mechanics and compressible flow. This will be illustrated through examples of aeronautical applications.
After successfully completing this module, students will:
1. have developed understanding of the thermodynamic concepts necessary to understand and interpret thermodynamic cycles
2. have gained skills in analysing a significant number of practical and ideal cycles power and cooling cycles involving air, steam and refrigerants
3. understand all aspects of aerospace propulsion including; supersonic aerodynamics, aero piston engines, gas turbine engines, ramjet, scramjet and rocket engines
4. be able to use engineering reasoning to critically access the advantages and disadvantages of the various cycles and engines
