Investigation of Partially Catalytic Boundary Conditions for High-Speed Flows

What is it about?

Differences caused by non-catalytic vs. fully catalytic wall boundary conditions were assessed using CFD for a 2D-wedge model for a range of Mach numbers (7 < Mach < 10) and altitudes (25 km < Alt. < 45 km). We found oxygen recombination coefficient must be accurate O(~1e-3) to produce a distinguishable solution in-between both extremes, non and fully catalytic, assumptions.
