ME 422Principles of Turbomachinery

3 credits · Mechanical Engineering · Penn State

Conservation laws pertinent to energy conversion and fluid mechanics are applied to pumps, centrifugal compressors, axial compressors and turbines, hydro turbines and wind turbines. Ideal performance is established, and conventional loss correlations are applied to define potential performance of turbomachinery. The applications of similarity and dimensionless parameters towards characterizing turbomachines are outlined. The course objectives are; 1. Review/acquire thermofluids concepts applicable to turbomachinery such as Reynolds transport theorem, First and Second laws, isentropic efficiencies, potential flow, dissipative flows. 2. Develop an understanding of working principles applicable to centrifugal, axial and mixed flow machinery. Extend concepts applicable to hydro and wind turbines. Develop approximations for both compressible and incompressible flows. 3. Gain an understanding of loss calculations.
