The two-thickness integral method of determining boundary-layer characteristics has previously been shown to provide reasonable results for stagnation-point flows even when the effects of equilibrium air dissociation are considered. This result implied that the method may have more general application and it therefore seemed advisable to explore additional characteristics of the method to further assess the extent of its applicability. The zero pressure gradient case, with its associated limiting cases, i.e., zero Mach number and zero heat transfer, has been used as a basis for this further evaluation primarily because of the availability for comparison of computations performed by exact methods. In general, it appears that of the profile representations considered, a two-parameter, sixth degree velocity profile gives the most desirable results for a flat plate when used with the present method.
