Summary. An accurate method of solution is developed for steady incompressible laminar boundary layers whose main-stream velocity U(x) is expressible as an odd polynomial in distance x measured along the wall, 0 0 The velocity distribution within the boundary layer is expanded in a similar series, co u = u 1 ~ F2n+l'(~?) ~:~"+1, 0, the coefficients of the first six terms being given as sums of multiples of known universal functions. The • relatively small contribution of the subsequent terms is estimated by using an idea of Howarth, whereby the cdefficients of the seventh and subsequent terms are assumed to have the same dependence upon the distance normal to the wall as does the sixth term. With this approximation the equation for the non-dimensional skin-friction is reduced to a very simple first-order non-linear ordinary differential equation. Details are worked out for the case of a main-stream velocity U = U0 ( ~- ~a), boundary layer separation being estimated to occur at ~: = 0.6551. The boundary-layer thicknesses and the skin-friction distribution are tabulated. Consideration is also given to main-stream velocities U = U0(~:- ~a + ~:s) for two values of c ~ for which the analysis takes a particularly simple form. Similar results are given for these two cases. Separation is predicted at ~ = 0.664 ~ when a = 0.0789, and at ~ = 0.6245 when c ~ =- 0.1210. 1. Introduction. It

The Effect of Nonuniform Viscosity on *Stagnation* *Point* Pressure

At low Reynolds numbers the total pressure decreases in a global sense due to the actions of viscosity, but it may increase locally in regions such as stagnation points.
