Steady‐state solutions of Buoyancy‐assisted internal flows using a fast false implicit transient scheme (FITS)

M.M. El‐Refaee, M.M. Elsayed, N.M. Al‐Najem, I.E. Megahid

A fast false implicit transient scheme FITS is developed to predict thetwo‐dimensional steady‐state solutions ofbuoyancy‐assisted laminar internal flows. This new scheme uses…

Numerical investigation of the transient conduction in a rotating cylindrical shell exposed to an incident time varying heat flux

Daniel Eriksson, Bengt Sundén

The transient temperature distribution in a rotating cylindrical shellwhich is heated by an incident time varying heat flux (nuclearpulse) as well as a constant heat flux, is…

Semi‐implicit second order finite volume jet stream computations

P.G. Tucker, C.A. Long

Semi‐implicit, second order temporal and spatial finite volumecomputations of the flow in a differentially heated rotating annulus arepresented. For the regime considered, three…

Natural convective heat transfer from a cylinder in an enclosure partly filled with a porous medium

P.H. Oosthuizen, D. Naylor

Heat transfer from a cylinder placed on the vertical centre‐lineof a square enclosure partly filled with a porous medium that is saturatedwith a fluid has been numerically…

A finite volume method for the solution of the extrudate swell problem on unstructured triangular meshes

G.K. Despotis, S. Tsangaris

The extrudate swell phenomenon is analysed by solving, simultaneously,the Navier‐Stokes equations along with the continuity equation bymeans of a finite volume method. In this…

A comparison of convergence acceleration schemes for eigenfunction expansions of partial differential equations

Alcino Resende Almeida, Renato Machado Cotta

Different possibilities for the enhancement of convergence rates ineigenfunction expansions are investigated in the realm of integral transformsolutions for partial differential…
