Implementation of AUSM+-Up scheme with implicit residual smoothing into OpenFOAM
Vojtěch Běták, Jiřı́ Fürst · ACC Journal · 2015
The standard installation of open-source package OpenFOAM consists of segregated solvers based on pressure-correction schemes.These schemes specify type of jobs that can be solved, mainly incompressible and subsonic compressible flows.This paper deals with the implementation of coupled scheme with AUSM + -up flux that allows solving fluid problems in all speed regimes.This scheme is complemented by the Implicit Residual Smoothing (IRS), which extends the region of stability.Therefore an increase in the speed of convergence is observed.Acceleration by factor 6 was achieved.
