This paper presents experimental results of the heat and mass transfer characteristics of a water–LiBr horizontal tube absorber made of small diameter tubes. The experimental set up includes a tube absorber, a generator, solution distribution system and cooling water system. Three different tube diam...
Under desalination plant conditions the coefficient h//o is found to be approximately half the value of h//i, and h//o is therefore the controlling coefficient. As a result of this analysis, and a survey of tests reported with profiled tubes, a likely shape of an enhanced heat transfer ...
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...

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 experimental investigation is performed into the pool boiling heat transfer performance of TiO 2 -R141b nanofluid containing 0 vol%, 0.0001 vol%, 0.001 vol%, and 0.01 vol% TiO 2 nanoparticles. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDS) observations reveal...
Helically-coiled tube is a kind of high-efficiency heat transfer tube. When fluid flows in horizontal helically-coiled tube it will be affected by gravity and centrifugal forces,and the flow direction changes from time to time,resulting in secondary flow and thus behaving different flow and heat...
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 ...
Heat transfer to a horizontal tube bundle located in the freeboard of a bubbling fluidized bed combustor The characteristics of heat transfer from bubbling gas-fired fluidized bed to a horizontal staggered water-tube bundle located in the freeboard region is e... AHA Hafez,FM El-Mahallawy,SGS ...
It has been established that in the region of pressures close to a critical one, heat transfer in a transient regime of motion of a single-phase flow in a horizontal coil pipe changes nonuniformly over the cross section of the perimeter. The main factors here are the influence of inertia ...
