An equation for the coalescence of particles under the influence of velocity gradients has been applied to the problem of coalescence of spray droplets in the turbulent fields surrounding two-fluid atomizers. Two derivations have been made, one which permits the estimation of the probable upper limit of coalescence, and a second which takes into account the effects of dilution of the spray in the jet which reduces the coalescence. The first consideration results in a relationship which may be evaluated easily the second gives rise to a partial differential equation which is not susceptible to analytical solution. A solution by iteration of the corresponding finite difference equation is discussed in the Appendix.
