Heat flux prediction in shock-boundary layer interaction and multi-jet
interaction with reversed flow
- Funding Agency: Indian Space Research Organisation
- Project Summary: Interaction of shock waves with turbulent flow can result in high localized
heat flux to the vehicle surface. This can occur in shock-boundary layer interaction and multi-jet
interaction flows. Computational fluid dynamic (CFD) simulations are often limited in predicting
the peak heat loads accurately. This is primarily because of the error in the turbulence
models used in the simulation. The project investigates the physics of turbulence heating at shock
waves and develops improved models for CFD application. Well established theory and DNS
datasets are used for this purpose. The new models are implemented in the in-house CFD codes at
IIT Bombay. The turbulence models can thus be evaluated in canonical configurations, for which
experimental measurements are available. The well-validated CFD methodology is applied to
practical configurations of interest to VSSC/ISRO.
