A multigrid method for the compressible Navier—Stokes equations coupled to the k—ε turbulence equations

J. Steelant, E. Dick

The steady compressible Navier—Stokes equations coupled to thek—ε turbulence equations are discretized within avertex‐centered finite volume formulation. The convective fluxes…

A chebyshev collocation method for moving boundaries, heat transfer, and convection during directional solidification

Yiqiang Zhang, J.I.D. Alexander, J. Ouazzani

Free and moving boundary problems require the simultaneous solution ofunknown field variables and the boundaries of the domains on which thesevariables are defined. There are many…

Stability characteristics of time integration schemes for finite element solutions of conduction‐type problems

G. Comini, M. Manzan

Stability characteristics of two‐level, time‐integrationalgorithms are investigated, with particular reference to explicit schemes.Conditions for stability are expressed on the…

Numerical simulation of turbulent flow for calibration of cross‐correlation flow measurements

A.J.C. Stekelenburg, T.H.J.J. Van der Hagen, H.E.A. Van Den Akker

The cross‐correlation flow measurement technique, applied formeasuring the coolant flow rate in a nuclear reactor, was calibrated with theuse of numerical simulations of turbulent…

Vectorized strongly implicit solving procedure for a seven‐diagonal coefficient matrix

H. –J. Leister, M. Perić

The paper presents an extension of Stone’s¹ strongly implicitprocedure for solving linear equation systems resulting from thediscretization of partial differential equations to…
