Felderhof, B.U. (author), Ooms, G. (author)The flow of a viscous compressible fluid in a circular tube generated by a sudden impulse at a point on the axis is studied on the basis of the linearized Navier–Stokes equations. A no-slip boundary condition is assumed to hold on the wall of the tube. An efficient numerical scheme has been developed for the calculation of flow velocity and...journal article 2011

Harinck, J. (author)The next generation of thermodynamic power cycles offers great potential as the conceptual basis for sustainable energy converters. Examples are the supercritical and superheated Organic Rankine cycle, the transcritical condensation cycle, the supercritical Brayton cycle, the Organic Stirling cycle and the transcritical vapor compression cycle....doctoral thesis 2010

Nannan, N.R. (author)Shock waves can be formed in all states of matter, be it in the single- or multi-phase condition, when the substance is subjected to a rapid change of state, e.g., a sudden pressure variation. In the case of shock waves in vapors and gases, because of the fact that the developed theory is often based on the ideal-gas equation of state, it is...doctoral thesis 2009

Humble, R.A. (author), Scarano, F. (author), Van Oudheusden, B.W. (author)The unsteady flow features of a series of two-dimensional, planar base flows are examined, within a range of low-supersonic Mach numbers in order to gain a better understanding of the effects of compressibility on the organized global dynamics. Particle image velocimetry is used as the primary diagnostic tool in order to characterize the...journal article 2007

Guillard, H. (author), Labois, M. (author)This paper presents a hierarchy of compressible two-phase flow models. It is shown that using Chapman-Enskog expansions in the limit of zero relaxation time toward the various equilibria that exist in these flows, a full set of models of decreasing complexity can be constructed. At the top of this hierarchy, we have a complete seven equation...conference paper 2006

Fürst, J. (author)This article describes the development of a high order finite volume method for the solution of transonic flows. The high order of accuracy is achieved by a reconstruction procedure similar to the weighted essentially non-oscillatory schemes (WENO). On the contrary to the WENO schemes, the weighted least square (WLSQR) scheme is easily...conference paper 2006

Fureby, C. (author)The present study concerns the application of Large Eddy Simulation (LES) and Implicit LES (ILES) to engineering flow problems. Such applications are often very complicated, involving both complex geometries and complex physics, such as turbulence, chemical reactions, phase changes and compressibility. The aim of the study is to illustrate what...conference paper 2006

Boersma, B.J. (author), Van der Hoeven, S. (author)Modeling of scalar transport is an essential point in the simulation of non-premixed turbulent combustion. The fuel and oxidizer streams are, in general, modeled with an equation for the mixture fraction $Z$. This mixture fraction is a bounded function, i.e. it can never become large than one or smaller than zero. Symmetric central differencing...conference paper 2006

De Tullio, M. (author), Christallo, A. (author), Balaras, E. (author), Pascazio, G. (author), (author), Iaccarino, G. (author), Napolitano, M. (author)In this paper we discuss some of the recent advances in the immersed boundary (IB) method. More specifically, we show the application of this technique to problems with strong fluid/structure interaction and to compressible flows using local mesh refinement. These extensions are a must for the success of the IB method in industrial applications.conference paper 2006

Hartmann, R. (author)We give an overview of recent developments in error estimation and in residual-based and goal-oriented (adjoint-based) adaptation for Discontinuous Galerkin discretizations of sub- and supersonic viscous compressible flows. We also give an outlook on the planned continuation of this research in the EU project ADIGMA.conference paper 2006

Majewski, J. (author)The paper deals with the algorithm for unsteady anisotropic adaptation. The adaptation is using the remeshing approach to create a new refined grid. The grid is generated in computational space defined by metric field based on the tensor error indicator. The verification of the method is done first for 2D supersonic flow in a channel with...conference paper 2006

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

The method is capable of computing the three dimensional, steady state, subsonic, linearized (Prandtl-Glauert) potential flow about general configurations. The method is characterized by the application of a Dirichlet boundary condition and of "compressible"...report 1987

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
