QGDsolver is OpenFOAM framework for simulation of fluid flows using regularized equations approach. It contains library for approximation of partial derivatives at face centers of unstructured grids and a set of OpenFOAM solvers: QGDFoam – solver for compressible viscous perfect gas flows in a wide Mach number range – from 0 to infinity. QHDFoam – […]
Developed set of programs is using hybrid method of approximation for convection terms, which combines Kurganov-Tadmor scheme for compressible flows and operator splitting technique – PIMPLE.
The library is intended for the calculation of acoustic pressure and sound pressure level generated by turbulent flow of gas or fluid in far and near field by means of different acoustic analogies or by solving wave equations numerically with boundary element method.
