“…As the flow exits the pores, it expands to adjust to the static pressure of the test section. This apparent pressure discontinuity on a macroscopic scale is actually a gradual expansion on a microscopic level, which was also investigated numerically in Rife and di Mare (2019). The PSP molecules that are located in the pores will be surrounded by air with slightly higher pressure than those on the surface.…”

This paper presents the performance of pressure-sensitive paint (PSP) for the direct measurement of species concentration on a porous surface with mass injection. It is used to measure the ability of an injected gas to reduce the mass transfer of freestream species to the surface. A porous alumina sample was sprayed with a PSP luminophore solution. The sample was installed into a flat plate model and exposed to hypersonic cross-flows in the Oxford High-Density Tunnel. Tests were conducted with no coolant injection, air injection, and nitrogen injection at increasing blowing ratios. Oxygen partial pressure maps on the transpiration-cooled surface were obtained for several conditions at unit Reynolds numbers between $$2.58{-}5.0 \times 10^7/ \mathrm{m}$$ 2.58 - 5.0 × 10 7 / m and blowing ratios between $$0.016{-}0.078\%$$ 0.016 - 0.078 % . The oxygen pressure decreases as the unit Reynolds number decreases and the blowing ratio increases. Graphic abstract

“…The derived velocities in (4.1) and (4.2) correspond to the Darcy velocity just below the interface between porous domain and external flow. In a subsequent step, these velocities could be used to account for the interface between porous domain and external flow by using a flow resistance model (Idelchik 1986) or a more complex interface model (Rife & di Mare 2019; Lācis et al. 2020).…”
