Solution of the general dynamic equation along approximate fluid trajectories generated by the method of moments [PDF]
, 2005 We consider condensing flow with droplets that nucleate and grow, but do not slip with respect to the surrounding gas phase. To compute the local droplet size distribution, one could solve the general dynamic equation and the fluid dynamics equations ...

Droplet Size Distribution in Sprays Based on Maximization of Entropy Generation
Entropy, 2003 : The maximum entropy principle (MEP), which has been popular in the modeling of droplet size and velocity distribution in sprays, is, strictly speaking, only applicable for isolated systems in thermodynamic equilibrium; whereas the spray formation ...

Convective Ripening and Initiation of Rainfall
, 2014 This paper discusses the evolution of the droplet size distribution for a liquid-in-gas aerosol contained in a Rayleigh-B\'enard cell. It introduces a non-collisional model for broadening the droplet size distribution, termed 'convective ripening'.

Spray characteristics of a multi-hole injector for direct-injection gasoline engines [PDF]
, 2006 The sprays from a high-pressure multi-hole nozzle injected into a constant-volume chamber have been visualized and quantified in terms of droplet velocity and diameter with a two-component phase Doppler anemometry (PDA) system at injection pressures up ...

FUEL DROPLET SIZE DISTRIBUTION IN DIESEL COMBUSTION CHAMBER
Bulletin of JSME, 1974 <div class="htmlview paragraph">In order to determine spray droplet size in a diesel engine, fuel was injected into high-pressure, room-temperature gaseous environments with a diesel engine injection system. Droplet size was measured using the liquid immersion sampling technique with a mixture of water-methylcellulose solution and ethanol used as
