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.
