Analysis of Multiphase Heat Transfer of TA2/Q235B Clad Plate Subjected to Impinging Liquid Jet Cooling

Abstract

Three-dimensional numerical simulations are conducted to calculate the surface heat transfer coefficient (HTC) of the water jet impinging on a TA2/Q235B clad plate. The accuracy of the simulation model is validated by experiment. The simulation results are basically in agreement with the experimental results. The effect of clad plate temperature and thickness, jet height, orifice diameter, and orifice velocity on the HTC is investigated. The numerical results show that the average surface HTC of TA2/Q235B clad plate is greatly affected by plate temperature, Reynolds number (orifice velocity and orifice diameter), and plate thickness, while it is less affected by jet height. The surface HTC decreases with the increase of clad plate temperature and thickness. The surface HTC increases dramatically with the increase of jet Reynolds number. At the same Reynolds number (more than 14500), the cooling effect of increasing the orifice velocity is stronger than increasing the orifice diameter, while at the same Reynolds number (less than 14500), the orifice diameter has the larger impact on the surface HTC than the orifice velocity.
