The demand for improved product quality and increased productivity has focused attention on the need for more efficient systems of spray cooling during continuous casting. Optimizing the hydrodynamic parameters of the jet during nozzle design helps to obtain better dispersion and economy in water consumption. If multiple nozzles are used in a conveyorized application, the overlapping liquid distribution pattern of the nozzles needs to be considered because the process may depend strongly on the relative local volume flux of the spray. The disposition of nozzles that create overlapping jet zones results in dispersion profiles that depend on the experimental conditions. In order to understand the fluid behavior in the overlap region, the present paper suggests a hydrodynamic investigation using a program of simulation based on the experimental correlations of pulverized water jets. The influence of the hydrodynamic parameters by varying the water pressure Delta P between 0.2 and 0.9 MPa is highlighted, which gives a very wide operating range. In addition, other parameters such as the nozzle's orifice-to-surface distance, H, and the nozzle opening angle, theta, are highlighted.
