Veldman, A.E.P. (author)Time-integration methods for partitioned dynamical systems and iterative methods for viscous-inviscid interaction are unified using the language of linear algebra. In this way all expertise built up in viscous-inviscid interaction methods becomes available for the integration of partitioned dynamical systems. This report applies some well...report 1989

Toda, Y. (author), Stern, F. (author), Tanaka, I. (author), Patel, V.C. (author)Results are presented from a towing-tank experiment of propeller-hull interaction conducted in order to provide detailed documentation of the complete flow field appropriate both for explicating the flow physics and validating computational methods. Mean-velocity and pressure field measurements were made for the with- and without-propeller...report 1988

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

Van Vledder, G.P. (author), Weber, S.L. (author)A detailed description is given of a set of programs called EXACT-NL, which computes fetch- or duration limited wave growth with an explicit expression for the resonant four-wave interactions. This guide is meant as a user's manual. lt describes the principles and usage of each program of the EXACT-NL model. We used the EXACT-NL model for the...report 1988

van Hulzen, J.J.P. (author)The informatics policy at NLR is focussed on providing an infrastructure for the development of information systems. A new component in the infrastructure is the method base system, designed to support the management and use of algorithm implemented in programs. The preliminary design analyses the functions of the method base system and...report 1987

Oskam, B. (author), van den Berg, B. (author)The symposium demonstrated the importance of research in the area of mechanical high-lift systems for transport aircraft to improve the total performance of current transports. Computational techniques are shown to provide new tools for high-lift design. With regard to drag reduction by laminar flow control it is concluded that the information...report 1985

van Leeuwen, H.P. (author)The concept of fugacity is explained. Application of compressibility and fugacity data in hydrogen embrittlement calculations is discussed. Equations of state are reviewed. Compressibility factors and fugacity coefficients are calculated. A best estimate is proposed.report 1983

Veldman, A.E.P. (author), Lindhout, J.P.F. (author)An outline is presented of a new code, called VISIAN, for the analysis of aerodynamic flows with strong viscous-inviscid interaction. The code is based on the recently developed quasi-simultsuieous method for the calculation of strongly interacting boundary layers. The feasibility of this method has already been demonstrated liy means of a...report 1983

Ottjes, J.A. (author)A model is derived to calculate the pressure losses originating from the dilute phase pneumatic transport of coarse particles in the horizontal stationary flow regime. The model is based on the balance of drag forces and frictional forces acting on the particles during pneumatic transport. The particles are characterized by the particle terminal...doctoral thesis 1982

Li, Y.C. (author), Herbich, J.B. (author)The interaction of a gravity wave with a steady uniform current is discussed in this paper. Analysis indicates there is no dominant difference in the results obtained when employing either the equation of conservation of wave energy flux or the equation of conservation of wave action flux. Numerical calculations of the wave length change by...report 1982

Booij, N. (author)A mathematical model for the combined refraction-diffraction of linear periodic gravity waves on water is developed, in which the influence of inhomogeneities of depth and current is taken into account. The model is used to compute partial reflection of waves a gully or an undersea slope, with influence of a current. The model is also applied to...doctoral thesis 1981
