Semi-analytical model of spray impingement on a flat surface
JAROSŁAW MIKIELEWICZ, DARIUSZ MIKIELEWICZ
Abstract
Two-phase flow of air and small droplets impinging normally on a plate has been considered. The problem has been postulated in such a form that it is possible to obtain an analytical solution for the trajectory of the droplet. Solutions in radial and longitudinal directions are independent from each other. The air flow is determined by a potential flow. The drop paths are determined from consideration of the force balance on a droplet. As long as viscous effects can be neglected the analytical solution is exac but when viscous effects start to play an important role the numerical integration of postulated equations is required.
