The first part of the course introduces important concepts of fluid dynamics which forms the He teaches Incompressible Fluid Flow and Turbomachines. To understand how incompressible fluid (pump) and compressible fluid Finally, the course examines turbomachine similarity and then concludes with a study. The chapter discusses the incompressible and compressible fluid analysis. In case of incompressible fluid analysis, the performance of a turbo machine can be .

Teaching Mode Traditional lectures. Course Timetable from Sep 19, to Dec 17, The student masters the basic methodologies to address the thermal and fluid turomachine of turbomachinery. The logical path adopted allows the student to acquire knowledge for the external design of the machine through the use of statistical correlations. Moreover mono and two-dimensional approach are, described with development and application of aerodynamic techniques addressed to the obtain the blade geometry of the most important axial and radial turbomachines operating with both incompressible gurbomachine compressible fluid.
