Sažetak
Formulation of an implicitly coupled incompressible and compressible pressure- velocity solver is presented in this paper. The formulation is an alternative to commonly used segregated solvers, where inter- equation coupling is resolved by Picard iterations. In coupled solver, the momentum and continuity (pressure) equations are solved simultaneously, in a single block matrix. Turbulence model equations and energy equation in compressible flow are solved in a segregated manner. The formulation is based on deriving the pressure equation as a Schur complement, including the Rhie-Chow correction. New formulation of the compressible pressurebased solver is proposed by assuming an isentropic compression/expansion, resulting in consistent reduction of the compressible form to incompressible form.
