Flow Analysis of Rocket Nozzle using ANSYS: A Computational Investigation of Exhaust Dynamics in Aerospace Propulsion

  • Unique Paper ID: 201466
  • Volume: 12
  • Issue: 12
  • PageNo: 5339-5346
  • Abstract:
  • Rocket nozzles are key for creating thrust, but the high-speed gas flow inside them is incredibly complex. Since real-world testing is so expensive, we used computer simulations to get a closer look. This project uses ANSYS Fluent to build a 3D model of a convergent-divergent nozzle and analyze the exhaust flow. We set up a simulation for compressible, turbulent flow (using the SST k-omega model) to watch how the gas speeds up from subsonic to supersonic. Our main goal is to understand how the nozzle's shape affects thrust and pressure, and to spot important things like shock waves. This helps us find better, more efficient nozzle designs.
