Abstract-
Our research efforts are aimed toward the development of accurate CFD tools to
better represent the physics of turbulent hypersonic flows.
Generally, the calibration of turbulence models for hypersonic applications has
been performed using direct numerical simulation data of incompressible flows
or using perfect gas wind tunnel data.
Thus, the models that are used today in engineering production codes do not
represent the effects of high compressibility and temperature levels in the
transitional and turbulent regimes.
As a result, the chemical composition of the gas, the skin friction, and the
heat transfer are not predicted accurately.
The philosophy of our research is to develop an understanding of the physical
flow phenomena and to use this knowledge to develop models that capture the
real flow physics.
Direct and large-eddy simulations of canonical flows are used to study the
turbulent/chemistry interaction and to develop and validate turbulence models.
A review of our recent progress will be given.
