Beyond pressureless gas dynamics : Quadrature-based velocity moment models
gas dynamics Quadrature-based velocity moment models
2010/11/19
Following the seminal work of F. Bouchut on zero pressure gas dynamics which has been extensively used for gas particle-flows, the present contribution investigates quadrature-based velocity moments ...
A new approach to the gas dynamics equation: An application of the variational iteration method
Variational iteration method Nonlinear gas dynamics equation
2010/9/14
In this paper, He’s variational iteration method (VIM) has been used to obtain solution of nonlinear gas dynamics equation. This method is based on Lagrange multipliers for identification of optimal ...

Remarks on self-similar solutions to the compressible Navier-Stokes equations of a 1D viscous polytropic ideal gas
self-similar solutions Navier-Stokes equations viscous polytropic gas
2010/9/13
This paper is concerned with the self-similar solutions to the compressible Navier-Stokes equations of a 1D viscous polytropic ideal gas. Our results show that there exist neither forward nor backward...
ON THE OUTER PRESSURE PROBLEM OF A VISCOUS HEAT-CONDUCTIVE ONE-DIMENSIONAL REAL GAS
Out pressure problem real gas
