A new model for heating and evaporation of a droplet on a superhydrophobic surface is proposed. The model uses the analytical solution to the spherically symmetric heat transfer equation with the source term which is implemented in the numerical code and used at each time step of the calculations.

Abstract\\r\\nAdding water to fuel droplets is known to lead to puffing and micro-explosion. Puffing and micro-explosion lead to a rapid increase in the liquid fuel surface area. This, in turn, leads to an increase in the fuel evaporation rate and the formation of a homogeneous fuel vapor/air mixture.
