...-form solutions for local and average Nusselt number valid for arbitrary values of Prandtl number and nonuniform heating conditions are mathematically derived here. The effects of various values of Prandtl number and the index n or m on the heat transfer coefficients are presented. The results...

...S. S. Feng; T. Kim; T. J. Lu This paper presents a cost effective semi-empirical analytical model for convective heat transfer in pin-fin heat sinks subjected to nonuniform heating set by a circular hot gas impinging jet. Based on empirical correlations taken from the open literature, temperature...

... = 10 5 and ( b ) Ra = 3 × 10 5 when K ∗ = 0.2 , ϕ = 45   deg , and A = 1.5 We have attempted to understand the impact of hydrodynamic anisotropy on the natural convection in a porous cavity, where flow is induced by nonuniform heating...

...Je-Young Chang; Ravi S. Prasher; Suzana Prstic; P. Cheng; H. B. Ma This paper reports the test results of vapor chambers using copper post heaters and silicon die heaters. Experiments were conducted to understand the effects of nonuniform heating conditions (hot spots) on the evaporative thermal...

... are considered with uniform and nonuniform heating of bottom wall. The numerical solution of the problem is illustrated for Rayleigh numbers (Ra), 10 3 ⩽ Ra ⩽ 10 5 and Prandtl numbers (Pr), 0.026 ⩽ Pr ⩽ 1000. In general, the intensity of circulation is found to be larger for nonuniform heating at a specific Pr...

... wall of the enclosure is cooled and another one is heated, or the bottom wall is heated while the remaining wall(s) are well insulated. In the case of a nonuniform heated bottom wall and sidewall(s), a limited number of case studies has been reported. Sarris et al. ( 13 ) have reported the effect...
