Answer: ISRO
Notes: The Indian Space Research Organisation (ISRO) developed PraVaHa, a Computational Fluid Dynamics (CFD) software, at the Vikram Sarabhai Space Centre. Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis (PraVaHa) simulates airflow for launch vehicles, crucial for designing their shape, structure, and thermal protection systems. It is used in the Gaganyaan program for analyzing human-rated launch vehicles. Currently, it simulates airflow for perfect and real gas conditions, with ongoing validations for chemical reactions in scramjet vehicles.
