Tutor:

Supervisor:

Department of Fluid Dynamics and Thermodynamics

Synopsis:

The study subjects aim is to expand the students´ knowledge gained from the previous Alfa versions of the bachelors subjects Fluid Mechanics and Thermomechanics. It generalizes the findings in the scope of compressible fluid flow; the attention is focussed on the several non-isentropic cycles as well as fundaments of non-stationary and multidimensional flows.

Requirements:
