Computation of flow past high speed vehicles requires the use of a reliable turbulence model.Unfortunately, most of the turbulence models are developed for incompressible flows.Application of these models directly to high speed boundary layers with large density gradients can lead to significant errors iphone 14 price texas in prediction of skin friction.

Several compressibility corrections have been suggested in literature to predict these turbulent flows at high Mach numbers.In the present work, we have used two such corrections for the Spalart-Allmaras turbulence model and studied their state park 59fifty fitted performance at high angles-of-attack.Flow past an ogive cylinder is considered for the study.
