BOUNDARY LAYER TRANSITION--FREE-STREAM TURBULENCE AND PRESSURE GRADIENT EFFECTS,

Abstract

A theory of boundary layer transition is presented which includes the effects of free-stream turbulence and pressure gradient. The basic notion underlying the development concerns the remoteness of the boundary layer vorticity from the surface. The theory agrees well with experimental data. The laminar boundary layer solutions of Pohlhausen and Falkner-Skan are used to calculate the effect of pressure gradient on transition. Engineering formulas are presented and one example is calculated showing the application of the theory to a body of revolution. The theory can also indicate the effects of Mach number and heat transfer. (Author)
