Subject aims expressed by acquired skills and competences

Objective: The course aims to extend students' knowledge in multi-dimensional flow of incompressible and compressible fluids in laminar and turbulent regime, and especially on analytical methods of solutions and numerical solutions. Especially in case of the flow of compressible fluids there is specified mathematical model of time-dependent problem. An important application is the solution of wrap and resistance of bodies and fluid interaction with a rigid body.
