Book Description

A method which permits approximation of local heat-transfer coefficients in the laminar-flow region around cylinders of arbitrary cross seciton from those wedge-type profiles is extended to include the effects of large temperature differences and transpiration cooling. Charts prepared from exact solutions of the laminar boundary-layer equations for wedge-type profiles which allow for these effects yield results with a minimum of calculation. Application of the method to circular and elliptic transpiration-cooled cylinders is made to determine local heat transfer coefficients and surface temperatures and to determine the variation in coolant flow required for maintaining a constant surface temperature.
