Current Context : 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

• The software is developed in ISRO’s Vikram Sarabhai Space Centre (VSSC).
• It can simulate external and internal flows on launch vehicles, winged and non-winged re-entry vehicles.
• PraVaHa has been used extensively in the Gaganyaan program for aerodynamic analysis of human-rated launch vehicles, viz, HLVM3, Crew Escape System (CES), and Crew Module (CM).
• It will replace most of the CFD simulations for aero characterization, which is currently being carried out using commercial software.
