Rozklad vířivosti: metody a fyzikální aspekty
Kolář, Václav
A brief survey dealing with vorticity-decomposition methods is presented. A particular emphasis is put on their physical aspects and practical applicability.
Přehled některých nových výsledků o asymptotické dynamice slabých řešení Navierových-Stokesových rovnic
Skalák, Zdeněk
The main goal of the paper is the presentation of several recent results concerning asymptotic dynamics of weak solutions of the homogeneous Navier-Stokes equations.
Dominant flow features of twin jets in crossflow
Kolář, Václav ; Savory, E.
A survey of the recent studies of "twin jets in crossflow" (TJICF) by the present authors is carried out and extended in terms of results of the velocity-field analysis based on decomposition techniques. Similarities and differences between the dominant mean-flow vortical features, vorticity and circulation associated with three basic ground arrangements (tandem, side-by-side and oblique arrangements) are examined, and the comparison with the single jet case is carried out as well.
Dvě poznámky o regularitě slabých řešení Navierových-Stokesových rovnic
Skalák, Zdeněk
The first note concerns the initial condition for the suitable weak solution of the Navier-Stokes equations. We show that it is possible to take a rather more general initial condition than the one used in [3]. In the second note we discuss a slight improvement of a famous regularity condition proved in [1]
