Kvalitativní řešení interakce smykové vrstvy se syntetizovaným proudem.
Falta, Jiří ; Maršík, František (vedoucí práce) ; Popelka, Lukáš (oponent) ; Uruba, Václav (oponent)
This thesis investigates possibilities of suppressing the boundary layer separation which is made by controling boundary layer stability. Orr-Sommerfeld equation is numerically solved for this purpose and its solution was tested on Blasius boundery layer which stability is described in many specialized publications. Transition to turbulence is found out by eN method. Single-variable description of velocity pro les on own surface, which is based on the aproximative properties of Falkner-Skan equation, was used. Process of transition on the aerofoil NACA 63-418 was solved as an example of using proposed computational programs.

On Principle of the Rolling Turbine
Falta, Jiří ; Maršík, František ; Sedláček, M.
A new principle of a fluid machine called "rolling turbine" is analyzed using two different approaches. The first one utilizes the stability theory for inviscid flow to explain the origin of the vorticity which is crucial for existence of the driving force. The second approach uses the perturbation theory for an approximate solution of the problem describing the machine working in its "pump" mode. The slender-channel theory is applied to simplify the Navier-Stokes equations.
