Coalescence in nonisothermal turbulent flow
Abstract
The coalescence of liquid droplets in turbulent gas flow due to temperature fluctuations (turbulent coalescence) is investigated analytically. Self-similar solutions are obtained for the Fokker-Planck equation describing this process. The principal trends of the process are a reduction in droplet concentration and an increase in mean droplet size. It is shown that the intensity of turbulent coalescence may substantially exceed the intensity of coalescence associated with the dependence of droplet growth rate on droplet diameter.
