Abstract

An apparatus was developed to measure the local surface temperature, local heat flux, and local heat transfer coefficient for a 3 × 3 array of circular, normal, single-phase liquid water jets impinging on a copper surface. The local thermal measurements were used to obtain the average Nusselt number for the central jet. An angled confining wall was used to manage the spent fluid by maintaining a consistent crossflow momentum ratio with downstream position, which prevents degradation in the thermal performance of downstream jets. A correlation describing the average Nusselt number as a function of jet Reynolds number, Prandtl number, confining wall angle, nozzle to plate spacing, and nozzle pitch for single phase circular water jets is presented.
