It is observed that, Kumar and Tiwari model (KTM) better validate the results than the others model. The average annual values of convective heat transfer coefficient for the passive and hybrid (PV/T) active solar still are observed as 0.78 and 2.41WmK, respectively at 0.05m water depth....
A new method for evaluation of heat transfer between solid material and fluid in a porous medium. J Heat Trans, 1999, 121: 978–983 CrossRef Younis L B, Viskanta R. Experimental determination of the volumetric heat transfer coefficient between stream of air and ceramic foam. Int J Heat ...
heat transfer coefficientautomatic extremum seeking algorithmThe engineering-physical fundamentals of substance synthesis in a boiling apparatus are presented. We have modeled a system of automatic stabilization of the maximum internal heat transfer......
The results indicate that placement of two inclined baffles augment the overall heat transfer coefficient significantly along with the local heat transfer distribution. The pattern of local Nusselt number ratio strongly depends on the position, orientation, and geometry of the second plate. Like single...
Prediction of Heat Exchanger — Heat Transfer Coefficient Decay Due to Fouling The reduction over time of the overall heat transfer coefficient in Bayer Process tubular heaters due to DSP fouling is discussed. A mathematical heat tran... GA O'Neill - Springer International Publishing 被引量: 1发...
The primary objective of this study is to analyze the thermal efficiency and entropy production in a convective–radiative exponential perforated fin with internal heat source based on convective heat transfer coefficient, surface emissivity and variable thermal conductivity. ...
where m, cp, T, Tamb, A, and h represent the mass, specific heat capacity, and temperature of the battery, the ambient temperature, the area that heat convection occurs, and the convective heat transfer coefficient, respectively. The thermal conductivity (kbat) and characteristic length of hea...
An experimental device for internal heated gravity heat pipe with concentric casing structure had been established. Startup and heat transfer performances of the heat pipe under the condition of natural cooling condition were tested. The variation patterns of evaporating heat transfer coefficient in evapo...
