Influence of tangential injection on heat transfer to a cone in the transition reynolds number domain

A gas mist produced by supplying a cooling gas through a separate slot or a system of slots along the surface is a widespread method of obtaining a mass-transfer heat shield. Application of the gas mist for heat-shield purposes can hence be combined with its use to control gasdynamic processes. One possible scheme is gas injection through a slot tangentially to the cooled surface so that the directions of motion of the injected jet and the main flow coincide.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 25–29, September–October, 1977.
