Relationship between deposition properties and operating parameters for droplet onto surface in the atomization impinging spray

Modeling on effervescent atomization: A review

“…Most modeling work focused on the external two-phase flow out of the effervescent atomizer exit [13,14,16,23,[27][28][29][30][31][32][33][34][35][36]. For gas-liquid two phase flow, there are two approaches to establish the numerical model.…”

“…The fitting technology will be used upon extensive numerical computations. Based on extensive computations, a formula relating droplet mean diameter to operating conditions and liquid physical properties is deduced with the curve fitting technique [34,35] …”

“…Without considering secondary atomization, these models could not account for the spray evolution along the downstream of the exit orifice, which is critical to the engineering applications of atomization sprays. Lin and his co-workers [27][28][29][30][31][32][33][34][35][36] proposed a three-dimensional model to predict the droplet mean size and other spray characteristics by describing both primary and secondary atomizations [27][28][29]. They described the breakup mechanisms for both Newtonian fluid and non-Newtonian fluid by different primary atomization models [30,31], discussing the characteristics of impinging spray field in detail and indicated the proper plate distance [32,33].…”

“…They also studied the evolution of droplets mean diameter along the axial distance, the mean size and statistical distribution of atomized droplets at cross sections, as well as calculating and analyzing the change of droplet velocity and to reveal their inner driving force [27][28][29]31]. They worked on the influence of operating conditions and liquid physical properties [31], concluded the factors for achieving good atomization effects [27][28][29][30][31][32][33][34][35][36], quantified the influences of various operating conditions and liquid physical properties on atomization effects and impinging outcomes [34,35], and extended the use of effervescent atomization to suspension plasma spray [30,37].…”

A Fitting Formula for Predicting Droplet Mean Diameter for Various Liquid in Effervescent Atomization Spray

“…For effervescent atomization sprays, abundant experimental results (Ref 11-13) and numerical simulations ( Ref 15,16) indicated that the evolution of the droplet SMD with the axial distance presented similar trends in various cases for different operating condition and liquid properties. The droplet diameter first decreases and then increases with the axial distance, the nadir of the curve resides approximately 1 cm downstream of the nozzle exit.…”
