Correct option is C
Correct Answer: C. PraVaHa
Explanation:
- The Indian Space Research Organisation (ISRO), through its Vikram Sarabhai Space Centre (VSSC), has developed a Computational Fluid Dynamics (CFD) software named PraVaHa.
- The acronym PraVaHa stands for Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis.
- This tool is designed to facilitate aerodynamic design and analysis for aerospace vehicles by simulating both external and internal flows on various platforms, including launch vehicles and re-entry vehicles.
Information Booster:
Purpose: PraVaHa enables the simulation of airflow around aerospace vehicles, which is crucial for understanding aerodynamic and aerothermal loads during different phases of flight, such as launch and re-entry. This understanding aids in designing the vehicle's shape, structure, and Thermal Protection System (TPS).
Applications: The software has been extensively utilized in ISRO's Gaganyaan program for aerodynamic analysis of human-rated launch vehicles, including the HLVM3, Crew Escape System (CES), and Crew Module (CM).
Technical Capabilities: PraVaHa is designed to operate on both CPU and GPU architectures of current and upcoming supercomputing facilities, ensuring flexibility and scalability. It is capable of simulating airflow under both Perfect Gas and Real Gas conditions. Ongoing validations aim to extend its capabilities to simulate chemical reactions occurring during air dissociation upon earth re-entry and combustion in scramjet vehicles.
Collaborative Framework: The software's framework is secure and flexible, promoting collaborative development with academic institutions and government laboratories. By making PraVaHa available to a broader section of society, ISRO aims to contribute to India's self-reliance in aerospace technology
