A priori analysis of subgrid-scale terms in compressible transcritical real gas flows
Physics of Fluids, 2021Of interest to the research community dealing with real gas flows, this study analyzes the influence of the physical complexity of real gases on the amplitude of subgrid-scale (SGS) terms present in the filtered Navier–Stokes equations to be solved in large eddy simulations.

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-time interferometer technique for compressible flow research
17th Fluid Dynamics, Plasma Dynamics, and Lasers Conference, 1984Strengths and shortcomings in the application of interferometric techniques to transonic flow fields are examined and an improved method is elaborated. Such applications have demonstrated the value of interferometry in obtaining data for compressible flow research.

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 ...

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.

Non-Darcy Compressible Flow of Real Gases in Propped Fracture
SPE Annual Technical Conference and Exhibition, 1982ABSTRACT The development of a simple hyraulically fractured gas well model is presented. A one-dimensional fracture flow model is used to investigate the effects of non-Darcy flow of a real gas in a hydraulically induced, vertical, propped fracture.

Global Smooth Solutions of Viscous Compressible Real Flows with Density-Dependent Viscosity
Zeitschrift für Analysis und ihre Anwendungen, 2009We consider an initial boundary problem of viscous, compressible, heat-conducting real fluids with density-dependent viscosity. More precisely, we assume that the viscosity \mu(\rho)=\rho^{\lambda} , where \

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.

2D real-time (RT) phase-contrast (PC) MRI is a promising alternative to conventional PC MRI, which overcomes problems due to irregular heartbeats or poor respiratory control. This study aims to evaluate a prototype compressed sensing (CS)-accelerated 2D RT-PC MRI technique with shared velocity encoding (SVE) for accurate beat-to-beat flow measurements ...

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] .
