The structure of laminar flow of gas from a porous mesh insert

The results are given of an experimental investigation of nonuniformities of velocity in the vicinity of an envelope of porous mesh materials under conditions of laminar flow of air from that envelope. The obtained data are generalized along with the available literature data. Techniques are planned and recommendations given for ensuring a local continuous outflow of gas coolant to a porous surface under conditions of transpiration cooling of the wall.
