Experimental Study on Aerodynamic Heating Induced by Dual Injections into Hypersonic Cross Flow

Figure 16

Surface St distributions induced by parallel dual injections with each spacing of (upper figures), schematics of heating patterns (middle figures), and one-dimensional St profile on the middle of dual injectors ( = 4.8, 9.6, and 14.4 deg) and a line through SJ1 ( = 0 deg) (lower figures). Unclear boundaries of region B are illustrated with broken lines in the middle figures. A section of the St profile at is not shown due to a measurement error.
