In this study, an analytical investigation is made of a method of shielding a surface from parallel beams of thermal radiation by distributed injection of a fluid containing absorbing particles into the boundary-layer flow over the surface near the stagnation point. Superposition of various solutions is used to obtain results for a wide range of parameter values from a relatively small number of functions. Three optical conditions of the surface are considered: Specular reflection, diffuse reflection, and black. It is found that injection of absorbing particles helps to shield the surface if the injection rate is relatively high.
