Efficient prediction of hypersonic transition on cones
Abstract
Prediction of hypersonic boundary-layer transition has remained challenging due to its nonlinear and chaotic nature- Small changes in flow conditions may lead to qualitative changes in transition mechanism and appreciable shifts in its location. This reality has frustrated theoretical, computational and experimental efforts- Linear theories that can predict the linearly most unstable waves can not accurately forecast the onset of turbulence or how it shifts with changes in the flow configuration. Expensive simulations and experiments that examine one flow configuration provide valuable fundamental knowledge for their specific conditions, but do not yield predictions for how transition location changes when new conditions are encountered, unless new expensive simulations or experiments are performed for the new configuration of interest.
