“…Several studies have attempted to derive more general droplet size-velocity distribution based on statistical approaches [4,6]. Since mid-1980s, the Maximum Entropy Principle (MEP) method has gained popularity in the field of atomization and sprays to predict droplet size and velocity distribution and has obtained reasonable success.…”

Abstract:Determining the distributions of size and velocity of droplets formed at the end of primary breakup region is followed in this paper. The droplet formation stage at the end of primary breakup is random and stochastic and it can be modeled by statistical means based on the maximum entropy principle (MEP). The MEP formulation predicts the atomization process while satisfying constraint equations based on conservations of mass, momentum and energy. This model is capable of considering drag force on produced droplets through gas-liquid interaction using new approach. The model prediction is compared favorably with the experimentally measured size and velocity distributions of droplets for sprays produced by the two nozzles of considerably different geometries and shows satisfactory agreement.

“…Numerous PDFs exist in the literature from which twenty were tested by the least squares method in MATLAB software environment. In accordance with the literature, 3 PDFs were investigated earlier [15], namely, the Nukiyama-Tanasawa (NT), the Rosin-Rammler (RR), and the Gamma (Γ) [13,26], shown by Eqs. (8)- (10).…”

“…The Γ and RR PDFs have two parameters, while the NT has four parameters. However, the simplification of parameter p NT = 2 is common in the literature [16,26] which negligibly altered the R 2 value.…”

“…They instead proposed an empirical gamma distribution function to predict the drop size distribution in a spray from pressure swirl atomizer. On the other hand, Liu et al [202] used the gamma distribution to determine the droplet sizes after primary atomization from an air-blast atomizer. They further considered secondary atomization following a finite stochastic break up (FSBM) model of primary droplets, when the diameter of the primary droplet is above the size of the maximum stable droplet.…”

Comprehensive modeling of spray formation in liquid fuel injectors involves modeling of (i) internal hydrodynamics of fuel injector (ii) break up of liquid sheet leading to primary and secondary atomization and (iii) prediction of size and velocity distributions of droplets in the spray. Comprehensive models addressing all the three aspects are rare though some work has been reported that incorporate two of the three aspects. However, significant volume of literature exists on the individual modules. In the present work, progress and current trends in the individual modules have been extensively reviewed and their implications on development of comprehensive models have been discussed. The unresolved issues and future research directions are also indicated.
