In this study we develop the theoretical framework required for analys
is of the time-based multipoint statistics of sprays. This is accompli
shed in the context of the ideal spray-a random assemblage of droplets
modeled as noninteracting point particles. It is shown that such a sp
ray may be decomposed into a series of independent single-class sprays
, each of which is driven by an inhomogeneous temporal Poisson process
. Complete spray behavior is found by superposition of these processes
. A function is derived that contains all possible information about o
ne of these single-class sprays, the realization density. All of the c
ustomary multipoint statistics-the autocorrelation, power spectral den
sity, fluctuation moments, etc.-may be developed from the realization
density by suitable integrations over its probability space. Derivatio
ns of these quantities from the realization density are reported in a
series of companion articles.
