FINITE ELEMENT ANALYSIS OF STIRRING INDUCED BY AN ALTERNATING MAGNETIC FIELD
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 2 Số 2 - Trang 155-169 - 1992
M.BERELOWITZ, P.BAR‐YOSEPH
The numerical investigation into the stirring induced by an alternating magnetic field, applied in the axial direction of a closed axisymmetric container of conducting fluid, is presented. The interaction between the azimuthal current and magnetic field results in Lorentz forces in the meridional plane which induce the fluid flow. The magnetic Reynolds number is assumed to be smaller than ...... hiện toàn bộ
Accurate and efficient solutions of unsteady viscous flows
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 11 Số 4 - Trang 286-307 - 2001
P.De Palma, G.Pascazio, M.Napolitano
This paper describes two accurate and efficient numerical methods for computing unsteady viscous flows. The first one solves the incompressible Navier‐Stokes equations in their vorticity‐velocity formulation, using a staggered‐grid finite‐volume spatial discretization to provide second‐order accuracy on arbitrary grids, and combines effectively an alternating direction implicit scheme for ...... hiện toàn bộ
Application of semi‐analytical methods for solving the Rosenau‐Hyman equation arising in the pattern formation in liquid drops
International Journal of Numerical Methods for Heat and Fluid Flow - - 2012
MehdiDehghan, JalilManafian, AbbasSaadatmandi
PurposeRosenau‐Hyman equation was discovered as a simplified model to study the role of nonlinear dispersion on pattern formation in liquid drops. Also, this equation has important roles in the modelling of various problems in physics and engineering. The purpose of this paper is to present the solution of Rosenau‐Hyman equ...... hiện toàn bộ

International Journal of Numerical Methods for Heat and Fluid Flow - - 2009
O.D.Makinde
PurposeThe hydromagnetic mixed convection flow of an incompressible viscous electrically conducting fluid and mass transfer over a vertical porous plate with constant heat flux embedded in a porous medium is investigated.Design/methodology/approach... hiện toàn bộ
The Stokes problem for a dusty fluid in the presence of magnetic field, heat generation and wall suction effects
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 10 Số 1 - Trang 116-133 - 2000
Ali J.Chamkha
This work focuses on the laminar flow of a two‐phase particulate suspension induced by a suddenly accelerated infinite vertical permeable surface in the presence of fluid buoyancy, magnetic field, heat generation or absorption, and surface suction or blowing effects. The governing equations for this modified Stokes problem are developed based on the continuum representation of both the flu...... hiện toàn bộ
Flow over solid blocks in open ended cavity
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 19 Số 5 - Trang 633-649 - 2009
S.Z.Shuja, B.S.Yilbas, S.M.A.Khan
PurposeThe purpose of this paper is to consider flow over heat generating bodies in an open‐ends cavity, which finds applications in electronics cooling and industrial processing. Heat transfer rates depend on the flow situation in the cavity, which is influenced by the cavity inlet and exit port locations, heat transferrin...... hiện toàn bộ
Natural convection of thermomicropolar fluid from an isothermal surface inclined at a small angle to the horizontal
International Journal of Numerical Methods for Heat and Fluid Flow - - 1999
M.A.Hossain, M.K.Chowdhury, RamaSubba Reddy Gorla
An analysis is performed to study the skin‐friction, the couple‐stress and heat transfer characteristics of a laminar free‐convection boundary layer flow of a micropolar fluid past an isothermal plate inclined at a small angle to the horizontal. When the inclination is positive, series solutions, one valid near the leading edge and the other at a large distance from it, are obtained. Intro...... hiện toàn bộ

A.C.NEVES, A.J.NOWAK
Steady‐state solutions of Buoyancy‐assisted internal flows using a fast false implicit transient scheme (FITS)
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 6 Số 6 - Trang 3-23 - 1996
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 the two‐dimensional steady‐state solutions of buoyancy‐assisted laminar internal flows. This new scheme uses the control volume based on power law technique in conjugation with the alternating direction implicit (ADI) and the successive grid refinement (SGR) procedures to solve the transient vorticity and energy transport ...... hiện toàn bộ
Finite element formulation for filling a thin section cavity
International Journal of Numerical Methods for Heat and Fluid Flow - Tập 7 Số 4 - Trang 344-366 - 1997
David T.Gethin, ShahrirAbdullah
Presents a quasi three‐dimensional formulation for filling a thin section cavity which is derived under the assumption that no transverse flow occurs in the gap. A no‐slip condition was applied on all surfaces occupied by the fluid and a slip condition on all air‐filled (empty) surfaces. The formulation was developed to analyse the sections which lie in the xy‐pl...... hiện toàn bộ
