Methods used to generate statistical values of planar spray characteristics, such as mean drop size and velocity, from discrete measurement points are established and evaluated. Round, flat, and multiori-fice air-atomized sprays are investigated experimentally, representing common but distinctly different sprays. The details of each spray plume are overresolved with an extensive matrix of measurement points, which are then down-sampled to evaluate the minimum number of required points and locations to calculate accurate planar spray statistics. Weighted-average values are generated using the local flux and discrete area at each measurement point, which provide holistic spray characteristics using relevant physical characteristics of the spray plume. It is found that measurements should be performed at approximately each 10% interval of the overall spray plume size to achieve errors less than 5%. Also, the measurements should be performed along one axis for an axisymmetric round spray, along both the x-and y-axes for a flat spray, and along a single axis from the center to edge for a multiorifice air-atomized spray for drop size, but along both the x-and y-axes for velocity. Finally, the methods are applied toward the combination of drop size distributions acquired at many points to generate a representative combined drop size distribution for a spray cross section.
