Simulation of porous transpiration cooling of the leading semicylindrical edge of a streamlined body

Experiments are carried out for simulating the efficiency of cooling the leading edge of a blunt streamlined body made of porous reticular material with an impermeable insert placed along the stagnation zone. Satisfactory results are obtained that make it possible to recommend the proposed method of organizing transpiration porous cooling of the leading edge of the blades used in high-temperature gas turbines for implementation.
