DNS: Supersonic Plane-Channel Flow with One Isothermal and One Adiabatic Wall

Return to: Data from DNS - Intro Page

The data on this page were provided by G. Coleman.

Direct numerical simulation is used to investigate the turbulent Prandtl number (Pr_t) above cold (isothermal) and hot (adiabatic) walls in a family of supersonic channel flows. A range of Reynolds numbers and mean temperature/density variations is considered. Additional details concerning the data, code, and computational methodology can be found in:
