Approximate solutions are presented for the transfer of heat in two regions, i. e., a region in which the inertial and viscous forces are of identical order of magnitude, and the region of creep flow. The experiments carried out with air over a wide range of Ra x numbers yield results ...

An analysis has been conducted of published heat transfer measurements obtained under clean conditions in smooth tube HTME evaporators. A calculation procedure has been used to determine the steam condensing coefficients, h//i, within the tube, and so derive brine evaporating coefficients, h//o, ...
Experimental data were obtained for the heat transfer coefficient between electrically-heated horizontal tube bundles and square fluidised beds of silica sand and alumina as a function of air fluidising velocity. Heat transfer data for a bundle of tubes are compared with a single tube under otherwise...
A horizontal U-shaped heat exchanger submerged in a pool is under development as a key equipment of a passive safety system. For the successful design of the heat exchanger and the safety analysis of the nuclear power plant, the reliable prediction of the heat transfer performance of the heat...
An investigation has been made to determine the effect of low frequency oscillations of relatively large amplitude on the rate of heat transfer from a small horizontal wire to water. Frequencies from 0 to 4.25 cps and amplitudes to 2.76 in. were employed. Temperature differences up to 140 deg ...
Fluid flow and heat transfer of natural convection around large horizontal cylinders were investigated experimentally. The main concerns were the turbulent transition and its influence on the local heat transfer. The experiments were performed in the range of modified Rayleigh numbers from 1.0×108 to ...
A dimensionless mathematical model is proposed to predict the local heat transfer coefficients between vibrated fluidized beds and immersed horizontal tubes, and the effects of the thickness of gas film and the contact time of particle packets are well considered. Experiments using the glass beads (th...
Heat transfer experiments were carried out for natural convection in an enclosure, simulating a dry shielded canister with 24 PWR spent fuel assemblies. The objectives of this study were to investigate the thermal hydraulic characteristics of natural convection in the canister and to establish an evalu...
