Analysis of water droplet evaporation through a theoretical-numerical model

An analytical model previously defined and numerically transposed via a Runge-Kutta 4-th order method is here employed to thoroughly describe a water droplet travelling in air from a sprinkler nozzle down to the ground. The study, aimed at a realistic description of the process, is completed by a number of analysis parameters which contribute to fully describe the system, the phenomenon and the mutual affections that characterise the study in relation to the droplet travel distance, the droplet time of flight, and the final droplet temperature. The few assumptions superimposed do not alter the reliable picture arrived at. The results, provided in the form of figures and comments, enable the reader to well understand the phenomenon and to realise which parameters prove more effective on conditioning the whole process. A general applicability of such results to define rational irrigation policies appears extremely evident and is supported by the treating provided.
