Abstract

Verification and validation studies applied to the Launch Ascent and Vehicle Aerodynamics (LAVA) computational fluid dynamics (CFD) solver is presented. A modern strategy for verification and validation is implemented incorporating verification tests, validation benchmarks, continuous integration and version control methods for automated testing in a collaborative development environment. The purpose of the approach is to integrate the verification and validation process into the development of the solver and improve productivity. The procedure uses the Method of Manufactured Solutions (MMS) for the verification of 2D Euler equations and 3D Navier-Stokes equations. A method for systematic refinement of unstructured grids is also presented. Inviscid vortex propagation and flow over a flat plate are included in the verification study. Simulation results using laminar and turbulent flow past a NACA 0012 airfoil and ONERA M6 wing are validated against experimental data compare to existing numerical results.
