Boerstoel, J.W. (author), Veldman, A.E.P. (author), van der Vooren, J. (author), van der Wees, A.J. (author)Current and mid-term developments in computational 3-D steady aerodynamics software at NLR, focusing on the efficient aerodynamic design of the next generation of transport aircraft, are surveyed on a global level. Following a brief review of the various levels of sophistication in physical flow modelling, and their relation to the aerodynamic...report 1986

Vaatstra, W. (author), Veldman, A.E.P. (author), van der Vooren, J. (author)The method of Glowinski, Periaux and Pironneau for the calculation of transonic flow, which is based on the constrained minimization of a cost function, is critically evaluated for a case in which the transonic small perturbation equation is used. The resulting minimization problem is discretized in finite element form and solved using a...report 1980
