We investigate the coalescence of drops undergoing random Brownian motion and evaporation. The evolution of the drop size spectrum is determined by solving a partial integro‐differential equation with a kernel that describes the pairwise coalescence of drops. Numerical results for fuel injection with n‐octane suggest that the size distribution of drops is determined by two competing processes, namely coalescence and evaporation.
