The single phase heat transfer from an upward facing, horizontal copper surface to arrays of impinging water jets was experimentally investigated. Experimental configuration allows for a free-surface unconfined jets flow. Square nozzles 50 × 100 μm arranged in four different geometries were used. Additionally, for the set of two jets array geometry was varied by adjusting the nozzle to nozzle distance. The area averaged heat transfer coefficient was found to be a strong function of working fluid mass flux and array geometrical aspect ratio. The proposed correlation agreed with the experimental data within 30% error bounds Obtained database of experimental data with analytical correlation allows the rational design of microjet modules for various industrial applications.
