PraVaHa Software:
SRO’s Vikram Sarabhai Space Centre (VSSC) develops PraVaHa (Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis), a Computational Fluid Dynamics (CFD) software for aerodynamic design and analysis of aerospace vehicles.
- PraVaHa simulates external and internal flows on launch vehicles, winged, and non-winged re-entry vehicles, aiding in the evaluation of aerodynamic and aerothermal loads during launch and re-entry.
- It is extensively used in the Gaganyaan program for analyzing human-rated launch vehicles and is designed to utilize CPU and GPU architectures for efficient simulation.
