“…Several experiments have been performed, by varying HFE-7100 mass flow rate. All the experiments yielded the behaiviour shown in figure (9). For 20 <q < 80 kW/m 2 the thermal resistance of the evaporator with offset strip fins is half the thermal resistance of the evaporator with no fins.…”

International audienceAn experimental study on saturated flow boiling heat transfer of HFE-7100 in vertical rectangular channels with offset strip fins is presented. The experiments have been carried out at atmospheric pressure, over a wide range of vapour quality and heat fluxes up to 1.8×10 W/m. The local boiling heat transfer coefficient has been obtained from experiments and analysed by means of Chen superposition method. Some correlations for convective boiling and nucleate boiling heat transfer coefficients have been considered. A good agreement has been found with Feldman et al. [3] correlation for convective boiling heat transfer and Kim and Sohn [8] correlations for nucleate boiling heat transfer

“…The deterioration of these surfaces performance is caused by a large number of mushroom bubbles staying above the surface microstructure, which prevented the bulk liquid from contacting the superheated wall for vaporization. Since 2002, Honda and Wei [8][9][10][11][12] have made a series of experimental study on boiling heat transfer enhancement by use of micro-pin-fins lm in thickness and 60-200 lm in height) which were fabricated by dry etching. From the boiling incipience to the critical heat flux, the micro-pin-finned surfaces showed a sharp increase in the heat flux with increasing wall superheat.…”

a b s t r a c tIn order to effectively enhance the boiling heat transfer under microgravity, experiments were performed using micro-pin-finned structure as heater surface in subcooled nucleate pool boiling of FC-72 under short-term microgravity condition utilizing the drop tower Beijing. Micro-pin-fins with the dimensions of 30 Â 60 lm 2 (thickness Â height) and the space of 30 lm were fabricated on the surface of square silicon with the dimensions of 10 Â 10 Â 0.5 mm 3 by using the dry etching technique. The results were compared with previous published data of smooth chip both in normal gravity and microgravity conditions. The micro-pin-finned chip showed a considerable heat transfer enhancement in the nucleate boiling region with higher upper limit heat flux and lower mean heater surface superheat compared to chip S under microgravity condition. The high-efficient heat transfer performance of FC-72 on the micro-pinfinned surface is independent of gravity, which stems from the sufficient supply of fresh liquid to heater surface due to the capillary forces.Crown
