Analytical modelling of heating and evaporation of drop clouds with temperature dependent gas properties

An analytical approach to evaluate the effects of droplet neighbouring on heating and evaporation is proposed, solving the conservation equations through the point source method, accounting for the dependence on temperature and composition of gas thermo-physical properties. The procedure to select the more appropriate boundary conditions on the drop surface is deepened and a method to mitigate the effect is proposed. The analytical solution for different arrays of droplets is compared for validation with an exact analytical solution for pairs of drops and with previous numerical solutions for drop arrays.
