Effervescent Atomization of Liquids

Time–frequency analysis of acoustic and unsteadiness evaluation in effervescent sprays

“…The bubble was thus elongated, and in some cases, deformed and split into smaller bubbles, as shown in Fig. 8 (Lorcher et al, 2005). Fig.…”

“…Their experiments demonstrated the process of gas flowing out of the exit orifice and bursting along the liquid jet. Lorcher et al (2005) combined an electrical measurement technique and high-speed camera to discuss how internal flow parameters (pressure and volumetric flow rates of liquid and gas) and flow regime affect the mean diameter of the spray droplet. The results of their experiment showed that the internal flow parameters vary under a certain condition and cause the mean diameter of the spray droplet to be time dependent.…”

Evaluation of effervescent atomizer internal design on the spray unsteadiness using a phase/Doppler particle analyzer

“…Effervescent atomization has recently become a focus of research interest because of the various advantages of the technique, fine and controllable spray at the low injection pressure compared with other atomization methods [12,13]. So far, many studies on effervescent atomization have focused almost entirely on the spray performance and the internal two-phase flow [14][15][16][17]. Sovani et al [18] concluded a summary about the wide variations in atomizer internal design, liquid properties and operating conditions on the effervescent atomizer performance.…”

Trends in Comprehensive Modeling of Spray Formation

“…Although atomization is possible in all of these regimes, the bubbly flow is optimal [75]. The most important parameter that governs the performance of effervescent atomizers is the air-to-liquid mass ratio commonly denoted as ALR in the literature [72,75,76]. Of all the flow and geometry parameters, ALR has the most significant effect on determining the droplet size [77,78].…”
