Numerical investigation of the interaction of coaxial vortex rings

M. Konstantinov

Presents the numerical investigations of interaction of several coaxial vortex rings in inviscid fluid. For the solution of non‐linear system of ordinary differential equations…

A general algorithm for compressible and incompressible flow. Stability analysis and explicit time integration

N. Nigro, M. Storti, S. Idelsohn

Addresses two difficulties which arise when using a compressible code with equal order interpolation (non‐staggered grids in the finite‐difference nomenclature) to capture a…

Simulation of fluid flow and gaseous radiation heat transfer in a natural gas‐fired furnace

Ge Song, Tor Bjørge, Jens Holen, Bjørn F. Magnussen

Reports that major advances have been achieved on computational simulations of multidimensional fluid flow, heat and mass transfer during the last 20 years. Focuses on the…

Computational issues in using a dual‐scale model of the segregation process in a binary alloy

S. Sundarraj, V.R. Voller

Explains that segregation processes during the solidification of a binary alloy occur at two distinct length scales: on the microscopic length scale of the crystal interface, in…

Conjugate natural convection of a power law fluid in a vertical finite thick channel with heat sources

Dang Huu Chung

Considers the conjugate natural convection motion of a power law fluid in a vertical finite channel, taking into account the heat transfer into channel walls as well as the effect…

Space‐time spectral element methods for unsteady convection‐diffusion problems

Pinhas Z. Bar‐Yoseph, Eduard Moses

Deals with the formulation and application of temporal and spatial spectral element approximations for the solution of convection‐diffusion problems. Proposes a new high‐order…

Feasibility of the LES for engineering problems

Toshio Kobayashi, Nobuyuki Taniguchi, Shigenori Togashi

Presents four examples which were researched in a large eddy simulation (LES) of turbulence for engineering applications. Explains that, in the former two cases, developments of…

Stabilization of higher‐order high resolution schemes for the compressible Navier‐Stokes equations

H. Daiguji, X. Yuan, S. Yamamoto

Proposes a measure to stabilize the fourth(fifth)‐order high resolution schemes for the compressible Navier‐Stokes equations. Solves the N‐S equations of the volume fluxes and the…
