A report describes an investigation of the validity of using statistical methods based on single-point probability density functions (PDFs) in mathematical modeling of mixing between a turbulently flowing carrier gas and the vapor from liquid drops suspended in the gas. The investigation included theoretical analysis and comparisons with results of direct numerical simulations (DNS) of a two-phase mixing layer.
