Hightemp Technique of High Temperature Gas Flows Numerical Simulation

A brief description of effective Navier-Stokes (NS) numerical technique for high temperature gas flows simulation (HIGHTEMP) is given. The NS codes have been developed for various gas-phase models from perfect gas to thermally and chemically nonequilibrium multicomponent and multitemperature gas medium. Slip effects, finite rate energy exchanges, surface catalysis and ablation can be taken into...

Numerical Study of Gas-solid Flow in a Cyclone Separator

This paper presents a numerical study of the gas-powder flow in a typical Lapple cyclone. The gas flow is obtained by the use of the Reynolds stress model. The resulting pressure and flow fields are verified by comparison with the measured results and then used in the determination of powder flow that is simulated by the use of a Stochastic Lagrangian model. The separation efficiency and trajec...

Numerical simulation of transient natural gas flow in pipelines using high order DG-ADER scheme

To increase the numerical accuracy in solving engineering problems, either conventional methods on a fine grid or methods with a high order of accuracy on a coarse grid can be used. In the present research, the second approach is utilized and the arbitrary high order Discontinues Galerkin Arbitrary DERivative (DG-ADER) method is applied to analyze the transient isothermal flow of natural gas th...
