Abstract

Drop size distributions are at least as important as mean drop sizes. Some spray applications require narrow size distributions (paint and respirable sprays), while some need wide ones (gas turbine engines). Other spray processes require very few small drops (agricultural or consumer product sprays) or very few large ones (waste incineration, IC engines). In this section, we discuss the concepts of drop size distributions, moments of those distributions, and characteristic drop diameters computed from them. This is followed by a summary of methods available for describing drop size distributions.
