GENERAL SOLUTION OF THE LAMINAR COMPRESSIBLE BOUNDARY LAYER IN THE STAGNATION REGION OF BLUNT BODIES IN AXISYMMETRIC FLOW

摘要

A modified Howarth-Dorodnitsyn transformation has been used to write the laminar boundary-layer equations for axisymmetric flow in terms of transformed variables, and the equations have been specialized for the vicinity of the stagnation point. Solutions to the equations depend on the wall enthalpy and on the variation of several of the gas properties through the boundary layer. The gas-property relationships are represented in the form of polynomials in powers of the deviation of the dimensionless enthalpy from a reference value, and the coefficients of these polynomials become parameters of the problem.
