Velldman, A.E.P. (author), Lindhout, J.P.F. (author), de Boer, E. (author)A description is given of VISIAN - a simulation method for 2-D viscous flows with strong viscous-inviscid interaction. The mathematical mode and the numerical algorithm are presented. VISIAN has been coupled with the inviscid-flow solver TRAPS. Results are shown for a number of airfoils; a comparison is made with results from other computations...report 1988

Lindhout, J.P.F. (author), de Boer, E. (author), van den Berg, B. (author)A computational method is presented for threedimensional turbulent boundary layers. The turbulence model is a simple eddy-viscosity formulation. An hybrid difference scheme is used, which has the robustness of first order schemes and accuracy of second order schemes. The boundary layer is computed in the region of determinacy of the initial data...report 1982

de Boer, E. (author), Lindhout, J.P.F. (author)The present report gives a brief survey of the theoretical background and the practical use of the boundary layer calculation system BOLA for the calculation of 3D laminar and turbulent boundary layers over non-developable STirfaces. A description of the driverprogram DRIBOLA which controls the BOLA processing, is included.report 1982

Lindhout, J.P.F. (author), Moek, G. (author), de Boer, E. (author), van den Berg, B. (author)This paper gives a description of a calculation method for 3D turbulent and laminar boundary layers on non-developable surfaces. A simple eddy viscosity model is incorporated in the method. Special attention is given to the organization of the computations to circumvent as much as possible stepsize limitations. The method is also able to proceed...report 1979

Lindhout, J.P.F. (author), de Boer, E. (author)This report consists of two parts. The first part describes a finite-difference 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 boundary-layer calculations are presented for flows over swept wings. The second...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
