Correlation of turbulent viscous layer thicknesses with mass transfer and angle of attack effects at hypersonic conditions

Aerodynamic Heating and Thermal Protection Systems

“…9 " 15 As shown here, the I|Re 2 values obtained are in close agreement with the experimental results of Smith and Liszt 12 and the theoretical results of Langhoff and Arnold. 15 In comparison with the works of Kivel and Camm 9 or Main et al, 10 in which shock tubes were used, the present results are much higher. Possible causes of error in the work of Kivel and Camm were discussed earlier.…”

“…4 " bands, which spread between 210 and 320 nm, is taken from the present work, whereas that of the E 1 Z+ -X 1 Z + band in the 170-210 nm range is taken from the theoretical work of Langhoff and Arnold. 15 The theory 15 vibrational quantum number combinations for which the experimental data are available; the experimental data cover only a few vibrational quantum number combinations, whereas the theory encompasses all possible combinations. Experimental work to verify the accuracy of the theory and experimental data for the E 1 Z + -X 1 T,+ band is in progress at NASA Ames Research…”

“…Gortler 15 and Ha'mmerlin 16 were the first to investigate analytically the stability of the two-dimensional, inviscid, irrotational stagnation flow on a flat plate. Substituting the basic Hiemenz similarity solution plus an infinitesimal perturbation proportional to e at cos(kz/a/v), where a is a constant of the stagnation flow, into the Navier-Stokes equation, they obtained a boundary-value problem with k as the eigenvalue.…”

“…5. The measured heating/pressure data correlations have been faired by Haslet, 6 Sayano, 8 Hoi den, 15 Markarian, 17 and Neumann and Burke 20 with typical results as (10) H-5 Dy/M = (P-? DI//PM) 1 ,rl\ U 1 ,rl\ U which is identical to Eq.…”
