    Incompressible fluids with shear rate and pressure dependent viscosity: regularity of steady planar flows

  • Original language description

    In the article the regularity of steady planar flow of fluids where the shearing stress may depend on the symmetric part of the velocity vector field and the pressure is studied. The periodic boundary conditions are considered. Using Meyers estimates itis shown that there exists a solution which is smooth. In the case where it is allowed to test weak formulation of the problem with a weak solution regularity of all weak solutions is proved.

    Nestlačitelné tekutiny s vazkostí závislou na tlaku a smyku: regularita 2dimensionálního stacionárního proudění

  • Czech description

    V článku je studována regularita ustáleného planárního toku tekutin jejichž tenzor napětí může záviset na symetrickém gradientu rychlosti a tlaku. Jsou uvažovány periodické okrajové podmínky. Pomocí Meyersových odhadů je ukázána existence hladnkého řešení. Pokud je dovoleno testovat slabou formulaci problému slabým řešením, je ukázána regularita všech slabých řešení.
