Abstract
Abstract : An object-oriented software library has been developed that is used to integrate a Paraxial Beam solver within both an overset (OVERFLOW) and an unstructured (AVUS) CFD model.The Paraxial Beam equation is used to propagate optical waveforms through the turbulent, unsteady flow fields produced by the structured overset and unstructured solvers. To achieve this new capability, an object-oriented, software library approach has been undertaken and has been used to develop the following components; a standalone mesh preprocessor, an easily integrated Paraxial Beam solver, a standalone Paraxial Beam solver and an assortment of post-processing tools. The new capability has been integrated within OVERFLOW and AVUS, and demonstrated for evaluating the Aero-Optical propagation through unsteady, turbulent flows past a circular cylinder and compared to aerodynamic and aero-optical data for a hemispherical turret.
