24 Class
25  Foam::ChomiakInjector
26 
27 Description
28  Injector model based on an idea of Jerzy Chomiak.
29 
30  Given the initial droplet size pdf in an interval d = (d0, d1),
31  the spray angle phi = phi(d), such that
32  the largest droplets have zero spray angle
33  and the smallest droplets have maximum spray angle.
34  i.e. phi(d=d1) = 0, phi(d=d0) = phiMax,
35  where phiMax is a model parameter.
