de Bruin, A.C. (author)The three dimensional flow field around delta wings with leadingedge vortex flow can be computed with panel methods. However, secondary flow separation may occur on the leeward surface of the wing. The associated free vortex sheet can be modeled in the potential flow calculation method, if the location of the secondary separation is provided by...report 1983

van den Berg, B. (author), Piers, W.J. (author), de Boer, E. (author)The attached flow around a swept wing has been calcTilated with allowance for the effects of boundary layer and wake. In part I a swept wing was considered with a turbulent boundary layer on both the upper and lower wing surface. The present part of the study deals with the calculation of the flow around the same swept wing with a laminar...report 1977

Lindhout, J.P.F. (author), de Boer, E. (author)This report consists of two parts. The first part describes a finitedifference scheme for the computation of 3D laminar boundary layers over developable surfaces. The stability of the first variation of the difference scheme is investigated. Some results of actual boundarylayer calculations are presented for flows over swept wings. The second...report 1976

van den Berg, B. (author)A theoretical study is made of the flow near the wall in a threedimensional turbulent boundary layer. An extended law of the wall is derived, which predicts the variation of the magnitude and direction of the velocity close to the wall. Furthermore an experimental investigation is described. Measurements were performed in a threedimensional...report 1976

Lindhout, J.P.F. (author), de Boer, E. (author)A method is presented to compute the 3D compressible turbulent boundary layer on an adiabatic wall under infinite swept wing conditions. The mathematical model of turbulence is based on a generalisation of Bradshaw's 2D shear stress equation. This results in a system of 5 equations valid along 5 distinct characteristics. A brief discussion is...report 1975

Lindhout, J.P.F. (author)A computer program has been prepared for the calculation of turbulent boundary layer development, based on a 3D version of the turbulent energy method. The method is briefly discussed. The computer program is described in detail. The present program is restricted to developable surfaces.report 1975

Elsenaar, A. (author), Boelsma, S.H. (author)On a wind tunnel model measurements have been made of the six components of the Reynolds stress tensor in a threedimensional incompressible turbulent boundary layer under infinite swept wing conditions in an adverse pressure gradient, with a threedimensional separation near the trailing edge. These measurements complement the mean velocity...report 1974

van den Berg, B. (author)The law of the wall has been extended to threedimensional flows, The effects of both the pressure gradient and the inertial forces have been considered. The deduced wall law is valid when the deviations from the simple twodimensional law of the wall are small. Agreement with measurements is found within the possible experimental error.report 1973

van den Berg, B. (author), Elsenaar, A. (author)On a wind tunnel model, especially designed to check calculation methods, measurements were made of a threedimensional turbulent boundary layer under infinite swept wing conditions in an adverse pressure gradient, with a threedimensional separation near the trailing edge. Accurate measurements of the external flow field, the mean velocity...report 1972
