The present paper is an experimental investigation of the hydrodynamic behaviour of two identical sprayers on a horizontal fixed plate, especially on the dispersion of water in the intersection area of jets. The aim of this work is to optimize heat transfer intensity by studying the dispersion of water droplets; we demonstrate experimentally that the fluid dispersion in the intersection jet area is different than the dispersion obtained by summation of both jets for different hydraulic atomizers.
Different hydrodynamic parameters were used with different variations as following; the water pressure (AP) from 0.05 to 0.3 MPa, the distance between sprayer and surface of plate (H) from 385 to 450 mm and the nozzles spacing (L) was calculated to maintain the overlapping diameter (Dovelap) of jets on plate between 180 and 220 mm.
