NUMERICAL SOLUTION OF REACTIVE LAMINAR FLOW BY A CONTROL-VOLUME BASED FINITE-ELEMENT METHOD AND THE VORTICITY-STREAMFUNCTION FORMULATION

A numerical procedure has been developed to solve laminar reactive flows. It makes use of a special interpolation Junction defined in a local flow-oriented coordinate system. Based on a control volume finite-element and an unstructured triangular domain discretization, it can handle irregularly shaped domains. The velocity-pressure coupling is addressed via the vorticity-streamfunction formulation and the disc retized flow equations are solved in a coupled way. The procedure has been successfully applied to simulate reactive and nonre-active flows. It was found to be accurate, stable, and fast. Comparison with experiments shows that it correctly stimulates the physics of the flows.
