Abstract

The motivation of the present research on flows with large density differences is the heating of the thermal shield of the European space shuttle HERMES during re-entry into the atmosphere. The question raised is whether the density differences, caused by the large temperature variations between the skin and the outer fluid which has been heated in passing through the shock, have specific effects on the turbulent rate of heat transfer to the surface. This situation will be simulated in the laboratory by injecting air or helium into boundary layers of helium or air respectively.
