...M.A.I. El‐Shaarawi; S.A. Haider Conjugate laminar forced convection heat transfer in the entry region of eccentric annuli is numerically investigated. Heat transfer parameters are presented for a fluid of Pr = 0.7 flowing in an annulus of radius ratio 0.5 for four values of dimensionless...

... the convective heat transfer in the fluid and vice versa. Accordingly, the energy equations for both the solid and the fluid have to solved simultaneously. © MCB UP Limited 1999 Annuli Forced convection Heat transfer Porous medium a_i=radial grid size scaling factor, (R_i...

... of the form: (3b) replaces P on the left hand side. The differences found in the second term of (3b) are due to the shift by 90° of the minimum resistivity (or maximum permeability). © MCB UP Limited 1998 Anisotropy Annuli Convection Porous medium A = added resistivity...

...M.K. Alkam; M.A. Al‐Nimr; Z. Mousa This study aims to numerically investigate the transient forced convection of non‐Newtonian fluid in the entrance region of porous concentric annuli. The hydrodynamic behavior of the flow is assumed to be steady and it is modeled using the non‐Darcian flow...

... to solve the governing Navier Stokes and energy equations. Combined convection in rotating spherical annuli is of great interest in both engineering design and geophysics. The problem can be divided into two cases. The first is the case in which the gravitational field acts in radial direction...

...Maged A.I. El‐Shaarawi; Esmail M. A. Mokheimer The paper utilizes a boundary‐layer model in bipolar coordinates to study the developing laminar free convection in vertical open‐ended eccentric annuli with one of the boundaries uniformly heated while the other boundary is cooled and kept isothermal...
