Syllabus |
1. Introduction: general classification of turbomachines; basic elements and working principle. 2. Governing equations of tubomachines: continuity equation; Euller's equation for turbomachines; energy equation for compressible flow machines; entropy equation. 3. Two-dimensional cascades of blades: dynamic analysis and performance parameters; drag and lift coefficients; eficiency of a cascade; design steps; direct and inverse methods. 4. Dimensional analysis and similitude conditions: similitude laws; non-dimensional global performance parameters; local design variables; turbomachine families; non-dimensional characteristic curves; experiments in wind tunnel. 5. Computational modeling: implementation of a compressor cascade of blades in dedicated software (Fluent); exploration of the results.
