Numerical simulation of sub-cooled boiling flow with fouling deposited inside channels

Abstract

Abstract:In this article, a numerical simulation has been performed to investigate the sub-cooled boiling flow in axisymmetric channels using the two-phase particle model. The equivalent diameter of the channel is 4.38 mm with 365.7 cm in length. The fouling deposited layer is filled with The Nusselt number in the fouling region without fouling deposited could be 50 times higher than that with fouling layer. The heat transfer performance of the channel with thickness of 0.225 mm fouling deposit layer is 5 times larger than that with thickness of 1.55 mm fouling deposit layer. It is also found that the inlet velocity has significant impact on the boiling and total pressure drops along the channel. Keywords

“…Additionally, the inflow velocity significantly affects the total and boiling pressure reductions along the channel. 17 van Gils et al 18 discussed the ability of the boiling procedure for batteries to thermo-condition (homogenize and cool). Accordingly, numerous experiments are carried out, and the outcomes are reviewed.…”

“…They observed that the pressure drop increased as the Reynolds and the capillary number increased. Liu et al (2016a) considered subcooled flow boiling at constant heat flux with deposited fouling layer. They discovered that the pressure drop increased significantly with an increase in inlet velocity.…”
