Název v původním jazyce

From quasi-incompressible to semi-compressible fluids

Popis výsledku v původním jazyce

A new concept of semi-compressible fluids is introduced for slightly compressible visco-elastic fluids (typically rather liquids than gasses) where mass density variations are negligible in some sense, while being directly controlled by pressure which is very small in comparison with the elastic bulk modulus. The physically con-sistent fully Eulerian models with specific dispersion of pressure-wave speed are de-vised. This contrasts to the so-called quasi-incompressible fluids which are described not physically consistently and, in fact, only approximate ideally incompressible ones in the limit. After surveying and modifying models for the quasi-incompressible fluids, we eventually devise some fully convective models complying with energy conservation and capturing phenomena as pressure-wave propagation with wave length (and possibly also pressure) dependent velocity.
