Abstract:

A semiempirical expression for boundary-layer transition location is developed based on the concept of a critical ratio of inertial to viscous shearing stresses at laminar breakdown. Extensive comparisons between predicted and measured transition locations on a 10-deg included-angle cone at transonic speeds are shown with the data predicted to within 10. Comparisons are also made with low subsonic and supersonic data which indicate the method is extendible to these flow regimes.
