Hoeijmakers, H.W.M. (author)An analysis is presented of results of a computational method to simulate the steady compressible vortical type of flow around a 65deg sharpedged cropped delta wing. The discussion emphasizes some more fundamental aspects of the numerical simulation such as the separation of the flow, the structure of the leadingedge vortex core and the flow...report 1991

Spekreijse, S.P. (author), Venis, A.C.J. (author)An efficient Roetype fluxdifference scheme for chemically reacting inviscid compressible flow in thermal equilibrium is presented. The numerical scheme is validated. Three well known chemical models are compared. The set of testcases concerned quasi onedimensional hypersonic nozzle flows, with and without strong normal Shockwaves.report 1990

Elsenaar, A. (author)As part of the joint International Vortex Flow Experiment, force and pressure measurements have been carried out on a 65 deg delta wing configuration in the transonic and supersonic wind tunnels of NLR. Out of these data three test cases were selected by the organizing committee of the GAMM WORKSHOP on the "Numerical Simulation of Compressible...report 1986

Boerstoel, J.W. (author)An analysis of various alternative approaches in grid generation is presented. A gridgeneration procedure for complex aircraft configurations could be based on a combination of three subprocesses, . decomposition of the flow domain into about 100 hexahedronal blocks, . trilineair transfinite interpolation to generate initial grid point...report 1986

Koppenol, P.J. (author)A computational method for solving the 3D Euler equations is studied. The method is based upon an upwind fluxdifference splitting scheme by Osher, exhibiting an implicit mechanism for numerical viscosity, in connection with an explicit timemarching finitevolume technique. The computer program is developed to run efficiently on both a scalar...report 1985

Vogels, M.E.S. (author)One of the experiments performed on board Spacelab, involves a partially filled annular cylinder which is subjected to prescribed motions (Ref. 1). The interest in this configuration arises from its practical use; for instance, the coolant in IRAS was stored in an annuluslike tank. In this report, a mathematical model for the transient liquid...report 1984

van Woerkom, P.T.L.M. (author)The attitude motion of interplanetary, spinning spacecraft under the influence of solar radiation and optimal thrusting, is investigated. A general model is formulated to describe the forces and torques exerted on the spacecraft due to solar radiation. The model is compared with model! available in the large body of literature on the subject. It...report 1978

van Woerkom, P.T.L.M. (author)The sttdy aims at a synthesis of the large body of literattire dealing with the analytical description of the perturbed motion of rigid, spinning spacecraft. The reader is familiarized with the various mathematical approaches to the problem. The class of restricted, perturbed motion is analyzed using the PoincarĂª asjrmptotic expansion procedxire...report 1972
