Abstract: We study two problems related to singular limits in fluid mechanics. First, we study the inviscid incompressible limit of the rotating compressible Navier–Stokes system for a barotropic fluid. We show that the limit system is represented by the rotating incompressible Euler equation on the whole space. Second, we investigate the regime of high Mach number flows for compressible barotropic fluids with density dependent viscosity. The Korteweg model as an isothermal model of capillary compressible fluids is considered.
