Finalizing Test Geometry for HAT CFD by Pratap Veer is a document available to read on EtoBox.

1) CFD was used to finalize the test geometry for a high altitude test of a launch vehicle, as the actual flight conditions could not be replicated. 2) Simulations showed that at flight conditions, the core jet would impinge on the strapons, but not at HAT conditions due to the lower jet pressure ratio. 3) To ensure impingement, the strapons were extended downward by 0.55 diameters based on CFD results, and additional modifications were made to one strapon to ensure direct impingement. Simulations of the
