Reduces wall heat flux
A vertical thin rod placed in a rarefied hypersonic rectangular cavity converts a closed cavity to an open one and reduces downstream wall heat flux.

The thin rod raises the shear layer from the cavity floor, turning a closed cavity into an open one
Flow pattern is dominated by rod height and position, not freestream velocity
Rod cross-sectional shape has little effect on shear layer and recirculation zones
