This report discusses direct numerical simulations (DNS) of a mixing layer between supercritical flows of oxygen and hydrogen. The governing conservation equations were those of fluctuation- dissipation (FD) theory, in which low-pressure typical transport properties (viscosity, diffusivity and thermal conductivity), are complemented, at high pressure, by a thermal-diffusion factor.
This work was done by Josette Bellan, Kenneth Harstad, and Nora Okong’o of Caltech for NASA’s Jet Propulsion Laboratory.
