Question: Uniform internal heat generation at 700Wm3 is occurring in a cylindrical nuclear reactor fuel rod of 70 - Finm-3 diameter, and under steady-state conditions the temperature distribution is of the form T(r)=a+br3, where: T ...
The effect of uniform internal heat generation on fully developed velocity profiles, temperature profiles, pressure drops and Nusselt numbers is studied for combined free and forced laminar convection with upward flow in inclined tubes subjected to a uniform heating at the tube wall. A numerical ...
The problem of unsteady, laminar, combined forced-free convection flow in a square cavity in the presence of internal heat generation or absorption and a m... Chamkha,J Ali - 《Numerical Heat Transfer Part A》 被引量: 208发表: 2002年 Analysis of Combined Free and Forced Convection for Ful...
摘要: in this paper,on the basis of the heat-flow distributing and superimposing principles,the solution of the heat-conduction differential equation of nonuniform internal generation is reached.关键词: distributing of heatflow superimposing nonuniform internal generation. heatconduction differential ...
difference method (ChFD) to solve the non-linear system of ordinary differential equations which involves both heat and momentum transfer in an incompressible, quiescent Newtonian fluid flow caused solely by a unsteady stretching of a horizontal sheet with non-uniform internal heat generation/absorption...
In recent years, the performance of the electronic devices has been improved greatly with shrinking package size, which inevitably leads to the heat flux density being discharged increases. How to removal the heat effectively has become a hot research topic [1–6]. Fins are applied widely in th...

the numerical simulation research was carried out aiming at non-uniform flow field structure produced by classical flat baffle distortion generator.Then flow field structure and distortion degree of different positions behind the flat baffle were analyzed and the change regulation of total pressure ...
The nonuniform inflow leads to the unfavorable expansion flow involved in the nozzle, and changes the internal pressure-field and shear stress along the ramp, and thereby, causes the degraded performance. The design method of the SERN considering the nonuniform inflow may be a way to eliminate ...
objects may be preemptively performed in high-heat-resistance solution materials, such as phosphonium ionic liquids, because the final step can be eliminated using the receiving substrate. Investigation of a uniform shrinking process using direct heating without a transfer process is also a worthwhile ...
