Book excerpt: Summary: a method of approximation for calculation of the laminar boundary layer with suction for arbitrary body contour and arbitrary distribution of the suction quantity along the contour and arbitrary distribution of the suction quantity along the contour of the body in the flow is developed. The method is related to the well-known Pohlhausen method for calculation of the laminar boundary layer without suction. The calculation requires the integration of a differential equation of the first order according to the isocline method. The method is applied to several special cases for which there also exist, in part, exact solutions: Plate in longitudinal flow and plane stagnation point flow with homogeneous suction. Furthermore the circular cylinder and symmetrical Joukowsky profile with homogeneous suction were calculated as examples.
