Aims of the teaching

The aim of the course is to introduce advanced methodologies (semi-analytical and numerical) for the analysis and simulation of heat engines, mainly axial thermal turbomachinery. Based on a detailed description of the fluid dynamics and heat and mass transfer phenomena present in these systems, the mathematical formulation and solution techniques at different levels are presented.

The first part of the course is focused on the thermodynamic analysis of gas and steam turbines at system level (regenerative cycles, cogeneration, gas turbines in aeronautic applications, etc.). The cycle analysis is performed both under design and prediction criteria.

The second part of the course presents the detailed analysis of system components. This level of analysis involves the detailed analysis of the fluid dynamic and thermal aspects that affect each component. First study the flow behavior in ducts of constant and variable cross sections (nozzles and diffusers), and also heat exchangers. Combustors are studied from a detailed analysis of the combustion phenomena and its numerical resolution in constant pressure combustion chambers. Furthermore, a detailed analysis of the flow in blade cascades in axial compressors and turbines is presented. Aspects related to blade cooling in turbines are also considered.
