Compressible fluid flows driven by stochastic forcing
stochastic Navier-Stokes equations compressible fluid random driving force
2012/6/21
We consider the Navier-Stokes system describing the motion of a compressible barotropic fluid driven by stochastic external forces. Our approach is semi-deterministic, based on solving the system for ...
Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
On statistical equilibrium in helical fluid flows
statistical equilibrium helical fluid flows
2009/11/9
The statistical mechanics of 3-D helical flows is re-examined for a continuum truncated at a top wavenumber. Based on the principle of equipartition of the flow enstrophy between helical modes, the em...
Similarity approach to the problem of second grade fluid flows over a stretching sheet
Two-dimensional boundary layer flows Viscoelastic second grade fluid
2010/9/15
This paper presents a study of the two-dimensional boundary layer flows of viscoelastic second grade fluid over a stretching sheet by the similarity method. Exploiting that some features of free-param...
