Angle factors between a small flat plate and a diffusely radiating sphere.

Abstract

gion II), & = (7T/2) 06 (region I) (see Fig. 2). The absorption coefficient was represented by the power law k — cpT according to Traugott. In the hypersonic regime, the deviation of the blackbody from the full results is practically zero since distances traveled in the shock layer are weighted by ki/ki. For supersonic flow, however, there is a significant difference, especially at small r, since k±/ki is much reduced. Along ]84, the influence of the body terms is more pronounced than along the other rays since the total weighting factor (&4/&i) (csc5/ [cos/3 -f sin/3 cot ]) is smaller there. From Eq. (3) constant limits for small arguments may be derived, and at distances of the order of one optical path length (l//ci) from the wedge, all radiative effects drop off very rapidly as expected fromEq. (4). • The pressure perturbations (xr) along the stagnation line were also computed for the supersonic case (see Fig. 3). They approach a constant limit for small r and drop off very
