News: The Indian Space Research Organisation (ISRO) has developed Computational Fluid Dynamics (CFD) software named Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis (PraVaHa).
About PraVaHa
- Capabilities: Simulates external and internal flows on various aerospace vehicles including launch vehicles, winged and non-winged re-entry vehicles.
- Aerodynamic Challenges: Aerospace vehicles face severe aerodynamic and aerothermal loads during launch and re-entry, including external pressure and heat flux.
- Application: Used extensively in the Gaganyaan program for aerodynamic analysis of human-rated launch vehicles such as HLVM3, Crew Escape System (CES), and Crew Module (CM).
- Operational Scope: Currently operational for simulating airflow under Perfect Gas & Real Gas conditions.
