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. To obtain a copy of the report, “Direct Numerical Simulations of LOX/H2 Temporal Mixing Layers Under Supercritical Conditions,” access the Technical Support Package (TSP) free on-line at under the Physical Sciences category.
