A new class of helium-cooled high heat-flux plasma facing heat exchanger (HX) concept is presented. These unique “Foam-In-Tube” HX concepts are composed of a thin tungsten shell integrally bonded to an open-cell tungsten foam core. High heat flux tests show maximum heat loads of 22.4 MW/m using 4 MPa helium at a flow rate of 27 g/s. Based on these impressive performance results, a unique and sc...

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...

In this paper, first the governing parameters characterizing low-finned tubes are reviewed. Second, the more important of the available performance correlations are compared with the available experimental data. The most reliable one can be employed to develop a pressure drop relationship, which has already been used in an algorithm for exchanger sizing. Also a means for the identification of a...

In the present era where energy demands are growing everyday it has become very important to capture every available energy from the hot source and utilize it for the process with minimum wastage. With this view, the combined serial two shell pass shell and tube heat exchanger (CSTSP) concept had been put forward and simulated using Fluent. Though the novel model of the heat exchanger has a hig...

In this numerical study, the heat transfer performance of shell-and-tube exchangers (STHXs) has been compared for two different tube arrangements. STHX having 21 and 24 tubes arranged in inline staggered grid considered analysis. Shell-and-tube exchanger with arrangement observed to provide lesser thermal stratification as arrangement. Further, study variation mass flow rate shell-side fluid co...
