“…Note that the fuel vapor is drawn by the large vortices and behaves as a weak upward flow. The upward flow is found to neutralize the upstream flow that is induced by the vortices, which is consistent with results from the study of transpiration cooling in a suddenexpansion channel [40]. Consequently, the recirculation structure is relatively insignificant comparing to that in the non-reacting case.…”

“…Two maxima of the Stanton number occur at the beginning of the coolant injection; one is near the step corner, and the other locates at the reattachment zone. The former is attributed to the greater coolant injection induced by the low pressure (the low-pressure center locates at x = 2.5-3.5 H) [12]. Accordingly, the temperature difference across the porous sheet is increased.…”

“…The aluminum oxide (Al 2 O 3 ) powder is seeded into the flow when conducting LDV diagnostics. Further details about the LDV measurement, including its uncertainty analysis, are available in [12]. Total 40 thermocouples (K-type, 125 lm) are attached to 20 stages at both sides of the porous sheet to measure the temperature of the bottom wall, while the flow temperature is accessed via a tiny probe installed with another thermocouple (K-type, 25 lm).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
