Abstract

A study has been performed to determine the feasibility of using computational fluid dynamics as a tool for predicting hypersonic boundary layer transition to turbulence and the resulting increase in heat transfer. Of particular interest is whether Detached Eddy Simulation can be used to overcome the scaling problems associated with Direct Numerical Simulation and Large Eddy Simulation of boundary layers. Fine-grid results for a boundary layer trip oriented 45 degrees to the flow inside a Mach 10 hypersonic wind tunnel show that Detached Eddy Simulation can predict transition in this perfect-gas flow.
