An Evaluation of the Two-Parameter Momentum-Integral Laminar Boundary Layer Calculation Method of Head.

Abstract

The two-parameter momentum-integral method of M.R. Head for the calculation of two-dimensional or axisymmetric, incompressible, laminar boundary layers is reworked into an analytical form, thereby eliminating the graphical data of Head's original method. The revised method is coded for digital computer solution and a number of test cases are computed. The numerical results for these test cases are compared with very accurate boundary layer solutions obtained by a finite-difference method and also results obtained using the Pohlhausen momentum-integral method. It was found that the Head method is vastly superior to the Pohlhausen method yet requires only about the same computational expense. Head's method yields very accurate results even for highly nonsimilar boundary layers. (Author)
