A study was performed of the atomization feature of liquid-column tower. It was found that the broken droplets can be classified into three types which called convex,twisted and broken. Proposed that the atomization process of liquid column tower consist of impact atomization and run into a wall atomization. Analysis of the atomization mechanism of the two processes, and the run into a wall atomization have droplet rebound,expand,splash stages. In addition ,the high degree of atomization of theoretical formula was amended. After modified, the theoretical and actual values are basically consistent.

Airborne inhalable particulate in the workplace represents a significant health hazard. One of the primary sources of this particulate is mist produced through the application of cutting fluids in machining operations. One of the important mechanisms for the production of cutting fluid mist is the atomization mechanism. In this paper, atomization is studied by applying cutting fluid to a rotating workpiece such as found in turning. An imaging system is presented for the study of the atomization mechanism. The imaging system extends the size measurement range typically achievable with aerosol sampling devices to consider larger particles. Experimental observations from the imaging system reveal that workpiece rotation speed and cutting fluid flow rate have significant effects on the size of the droplets produced by the atomization mechanism. With respect to atomization, the technical literature describes models for fluid interaction with the rotating workpiece and droplet formation via drop and ligament formation modes. Experimental measurements are compared with model predictions. For a range of rotation speeds and fluid application flow rates, the experimental data is seen to compare favorably with the model predictions.

Insight Into

Understanding the disintegration mechanism, spray penetration, and spray motion is of great importance in the design of a high quality diesel engine. The atomization process that a liquid would undergo as it is injected into a high-temperature, high-pressure air, is investigated in this work. The purpose of this study is to gain further insight into the atomization mechanism, the variation over time in droplet size distribution and spray penetration. This is done based on effect of chamber pressure, injection pressure, and type of fuel. A laser diffraction method is used to determine droplet mean diameters, single injection with synchronized time mechanism allowed the time dependent studies. Obscuration signals are obtained through a digital oscilloscope from which arrival time of spray can be measured. The spray penetration correlation obtained is compared to other correlation’s obtained from different other techniques used in the literature.

Pharmaceutical Production

Microencapsulation techniques are widely applied in the field of pharmaceutical production to control drugs release in time and in physiological environments. Ultrasonic-assisted atomization is a new technique to produce microencapsulated systems by a mechanical approach. Interest in this technique is due to the advantages evidenceable (low level of mechanical stress in materials, reduced energy request, reduced apparatuses size) when comparing it to more conventional techniques. In this paper, the groundwork of atomization is introduced, the role of relevant parameters in ultrasonic atomization mechanism is discussed, and correlations to predict droplets size starting from process parameters and material properties are presented and tested.

Auxiliary Mechanism

The paper advances a new atomization mechanism combining the centrifugal, the oscillating and the impact breakage atomization as a trinity, breaking through the traditionally single atomization model. The atomization mechanism raised here makes full use of the comprehensive effects of the centrifugal atomization, the oscillating atomization and the impact breakage atomization, synthesizing the superiorities of the three as an organic and powerfully efficient whole, and making their mutual reactions stronger step by step. Among the three, the impact breakage atomization is a new auxiliary mechanism, which can considerably improve the droplet’s atomizing process after the centrifugal and the oscillating atomization, producing much better an atomizing result. It is very convenient, simple and direct to fulfill “the-three-in-one”. This atomization mechanism not only can achieve the goal of even atomization and much tinier droplets, but can be energy-efficient with low cost and less labor intensity as well. Therefore it is a highly practical and useful method.
