Most conventional Computational Fluid Dynamics (CFD) algorithms applied in the aerospace industry use the density-based formulation to solve of Navier-Stokes equa- tions. While these algorithms are ideal for solution of compressible flows, they re- quire special care, such as preconditioning, for incompressible cases. Pressure-based methods, however, are ideal for simulating low-speed flows and do not require special care for compressible cases, making them increasingly popular for simulating flows at all speeds. The motivation of this thesis is to integrate a pressure-based coupled solver into an existing density-based solver, FlowPsi, using the LOCI Framework. The LOCI Framework is a rule-based programming model that simplifies parallel computations. The thesis begins by implementing the well-known SIMPLE algo- rithm and outlining the challenges of pressure-based methods using 1-dimensional derivation. The SIMPLE algorithm is then validated using several benchmark cases, and a pressure-based coupled algorithm is presented and implemented into FlowPsi. Several benchmark cases are solved, and the pressure-based coupled algorithm de- veloped by Darwish and Moukalled is validated for the laminar case. The study is concluded with the ongoing implementation of turbulence models.
