Abstract:
1. A computational fluid dynamics (CFD) method for analyzing fluid dynamic performance of a body comprising: determining a freestream turbulence intensity; determining a momentum thickness; determining a turbulence length scale; based on said freestream turbulence intensity, said momentum thickness, and said turbulence length scale, determining a first momentum thickness Reynolds number associated with a first estimated laminar/turbulent transition location along the body; determining an estimated laminar separation location; determining a spatial domain for running a turbulent flow model for modeling the fluid dynamic performance of the body, the determining of the spatial domain comprising: running the turbulent flow model in the determined spatial domain to determine the fluid dynamic performance of the body, wherein: at least in one instance, said estimated laminar separation location is upstream of said first estimated laminar/turbulent transition location.
