Recently, the Indian Space Research Organisation (ISRO) has developed Computational Fluid Dynamics (CFD) software named (PraVaHa).

About Computational Fluid Dynamics (CFD)

  • A Tool for Prediction: CFD is a tool to predict the aerodynamic and aerothermal loads which solve numerically the equations of conservation of mass, momentum, and energy along with the equation of state.

PraVaHa

About PraVaHa

  • PraVaHa stands for ‘Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis’.
  • Function: 
    • Simulate Flows: It can simulate external and internal flows on launch vehicles, winged and non winged re-entry vehicles.

  • Implications: 
    • Gaganyaan Programme: PraVaHa has been used extensively in the Gaganyaan program for aerodynamic analysis of human-rated launch vehicles, viz, HLVM3, Crew Escape System (CES), and CM.
    • PraVaHaScramjet Vehicles: Validations of the code are underway for simulating the effect of chemical reactions that occur during air dissociation upon ‘earth re-entry’ and ‘combustion’ as in scramjet vehicles.
  • Significance: 
    • Replacement of CFD Simulations: PraVaHa is expected to replace most of the CFD simulations for aero characterisation, which is currently being carried out using commercial software. 
    • Solutions to Complex Aerodynamic Problems: This software is expected to help academia and other institutions, engaged in the design of missiles, aircraft and rockets, to find solutions to complex aerodynamic problems.
