“…The present experimental data fit well this relation by taking the coefficient K= 1.08 over a range of q=l0~40W/cm 2 , while the theoretical prediction by Chang et al ( 6 ) gives K = 0. 7320 on the basis of laminar fluid heated by a vertical plane in a semi-infinite bath.…”

The temperature fluctuation is enhanced by imposing a weak magnetic field of B = 0.1-0.3 T for both parallel and transverse fields and almost completely suppressed with increasing to B = 1 T in the case of the transverse field but its low frequency component still remains large, becoming oscillatory, up to B = 3 T in the case of parallel field. The heat transfer shows a similar trend to the temperature fluctuation. It increases singularly by a weak B especially in the perpendicular sector to the transverse magnetic field and decreases with increasing B. In the case of parallel magnetic field, the heat transfer increases in a weak field of B = 0.1 -0. 5 T, the same as in the transverse magnetic field, but it does not decrease so much in a strong field of B = 1-3 T, presenting a rather higher value than in B = 0 T.

“…Fujii and M. Fujii [14] analyzed the solutions obtained by various researchers [8,15,[16][17][18][19] and suggested the following expression of Nusselt number: (19) The application of the direct integration method in case of a constant heat flux on a surface also allowed us to find the temperature distribution corresponding to the given value of the heat flux. (20) Figure 3 shows that the temperature on the wall at y = 0 increase when Pr >1, and remains almost the same when Pr <1.…”

“…Churchill and Ozoe [10,11] generalized the data of works [4,8,13] and suggested an accurate Nusselt number formula which is valid for all Prandtl number in a laminar flow. Fujii [14] analyzed the solutions obtained by many researchers [8,15,[16][17][18][19] and proposed a theoretical Nusselt number correlation, in case of a constant heat flux. Recently, Oleg, Martynenko and Khramtsov [20] studied natural convection problems for different geometries by means of analytical, numerical and experimental analysis.…”

In this paper, we investigate theoretically the natural thermoconvection phenomena near a vertical plate for two thermal boundary conditions at the sidewalls. A specifically developed analytical model based on the new integral method form is used for the solution of the momentum and energy transfer governing equations. From an adequate choice of velocity and temperature expressions, two new Nusselt-Rayleigh relations, depending on the sidewalls conditions, are derived for all Prandtl numbers. Comparisons among the different thermal configurations considered are reported. In particular, with reference to the typical configuration wherein the sidewalls are isothermal and in uniform heat flux, it is found that the NusseltRayleigh coefficient given via this method indicates a good agreement with the theoretical and experimental results for all Prandtl numbers.
