LAMINAR-TURBULENT BOUNDARY LAYER PROPERTIES ON AXISYMMETRIC FOREBODIES AT HIGH REYNOLDS NUMBERS.

An analytical model capable of simulating laminar-turbulent boundary layer properties on axisymmetric bodies over a wide range of Reynolds numbers was developed based upon the differential method of T. Cebeci-A. M. O. Smith. Several new dimensionless parameters were formulated which have significant impact upon the computations and clearly show the effects of body shape and body Reynolds number. Numerical results showing the effects of body shape and body Reynolds number (10-150x10**6) upon the boundary layer properties of an elliptical forebody (t equals 0. 5) in axial flow are presented. In each case, the location of the onset of transition was prescribed. The model performed well over a wide range of body Reynolds numbers and provided some new data which is beyond present experimental capabilities.
