Abstract:
In this report, two matters are dealt with which were left in an unsatisfactory state in the Appendices of Reference 1. The first concerns the conditions obtaining near the front of a flat plate in a uniform stream with constant continuous suction through the plate. We now satisfactorily prove that the boundary-layer velocity profile tends to the well-known Blasius profile as the front end of the plate is approached. The second matter concerns the solution of the boundary-layer equations of motion when 'similar' velocity profiles are assumed - it is shown that only two types of outside stream velocity distributions lead to 'similar' profiles, under ordinary conditions.
