    reactinLagrangianQGDFoam

Description
    Solver for unsteady 3D turbulent flow of perfect gas governed by
    quasi-gas dynamic (QGD) equations at all Mach numbers (from 0 to
    infinity) coupled with chemistry reactions.

    QGD system of equations has been developed by scientific group from
    Keldysh Institute of Applied Mathematics,
    see http://elizarova.imamod.ru/selection-of-papers.html

    Developed by UniCFD group (www.unicfd.ru) of ISP RAS (www.ispras.ru).
