Rotary Atomizer Drop Size Distribution Database

Wind tunnel measurements of drop size distributions from Micronair AU4000 and AU5000 rotary atomizers were collected to develop a database for model use. The measurements varied tank mix, flow rate, air speed, and blade angle conditions, which were correlated by multiple regressions (average R2 = 0.995 for AU4000 and 0.988 for AU5000). This database replaces an outdated set of rotary atomizer d...

A new parametrization of the rain drop size distribution

This paper revisits the problem of nding a parametric form for the rain drop size distribution (DSD) which 1) is an appropriate model for tropical rainfall, and 2) involves statistically independent parameters. Using TOGA/COARE data, we derive a parametrization which meets these criteria. This new parametrization is an improvement on the one that was derived in [3], using TRMM ground truth data...

Examination of the – Relation Suggested for Drop Size Distribution Parameters

Raindrop size distributions are often assumed to follow a three-parameter gamma distribution. Since rain intensity retrieval from radar observations is an underdetermined problem, there is great interest in finding physical correlations between the parameters of the gamma distribution. One of the more common approaches is to measure naturally occurring drop size distributions (DSDs) using a dis...

A Maximum Entropy Modelling of the Rain Drop Size Distribution

This paper presents a maximum entropy approach to Rain Drop Size Distribution (RDSD) modelling. It is shown that this approach allows (1) to use a physically consistent rationale to select a particular probability density function (pdf) (2) to provide an alternative method for parameter estimation based on expectations of the population instead of sample moments and (3) to develop a progressive...
