Subsonic flow of a real compressible gas in a vertical pipe
Russian Physics Journal, 2012The problem of stable motion of a real gas that obeys the van der Waals state equation in a vertical pipe is considered with allowance for the gas compressibility. The dependences obtained allow contributions of different processes to the formation of the pressure field and the character of density and velocity variations depending on the observation ...

A Real Ghost Fluid Method for the Simulation of Multimedium Compressible Flow
SIAM Journal on Scientific Computing, 2006In the previous ghost fluid methods (GFMs) developed, the focus is on the definition of ghost fluid states while the pressure and velocity in the real fluid sides are taken for granted, except for the correction made to the density at the real fluid nodes next to the interface to overcome the possible problems related to overheating.

An efficient algorithm for compressible flows with real gases
International Journal for Numerical Methods in Fluids, 1989AbstractAn efficient algorithm is presented for the solution of the Euler equations of gas dynamics with a general convex equation of state. The scheme is based on solving linearized Riemann problems approximately, and in more than one dimension incorporates operator splitting.

Widening the scope of a standard: Real time flows tunneling, compressing and multiplexing
2012 IEEE International Conference on Communications (ICC), 2012The use of the Internet for delivering real-time traffic flows makes it necessary to fragment the information into small pieces, thus making the traffic have a bad efficiency. In order to avoid this, the IETF defined TCRTP as a mechanism capable of compressing headers and multiplexing a number of RTP packets into a bigger one, which was sent using a ...

Journal of Computational Physics, 2013
Abstract The topic of this paper is to propose an extension of the classical one-dimensional Navier–Stokes boundary conditions (1-D-NSCBC) for real gases initially developed by Okong’o and Bellan [1] to a 3-D-NSCBC formulation based on the work of Lodato et al. [2] and Coussement et al. [3] .

Compressible duct flow of a real gas in a Lagrangian frame
Communications in Numerical Methods in Engineering, 1993AbstractAn approximate Riemann solver is presented for the compressible flow equations with a general (convex) equation of state in a duct of variable cross‐section and within a Lagrangian frame of reference. The scheme is applied to a well‐known shock tube problem.

Nonlinearity, 2003
The author examines the free-boundary problem for viscous gas with nonlinear dependence on temperature in the equation of state. The flow expands freely from a finite domain as time evolves. First, the problem is reformulated by using Lagrangian variables.

Medical Engineering & Physics, 2012
As a widely accepted prophylaxis for deep vein thrombosis, the underlying mechanism of compression stocking still remains unclear. In this study, computational fluid dynamics was applied to in vivo data to provide quantitative insight into the hemodynamic response of the deep venous system to static external compression.

A shear flow problem for compressible micropolar real gas
In this paper we analyse the micropolar, viscous, polytropic and thermally conductive real gas, assuming the generalised form of the pressure function in the sense that pressure is the ane function of temperature and the power function of mass density.Dražić, Ivan +2 more
