Book Synopsis Numerical Study of Effervescent Atomization by : Seyed Milad Mousavi
Download or read book Numerical Study of Effervescent Atomization written by Seyed Milad Mousavi and published by . This book was released on 2014 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomization is a process where the bulk of liquid jet disintegrates into liquid sheets, ligaments and droplets. It has enormous applications in industries and processes such as combustion, heat transfer systems, transport, biological systems and particularly our interest, coating processes. The Effervescent nozzle is a type of twin-fluid atomizer and has shown a superior performance in handling and spraying different liquids without any clogging issues; which is particularly interesting in thermal spray. In spite of significant number of experimental works, a few numerical works have been carried out. That makes it crucial to conduct a comprehensive numerical study on Effervescent atomizer. The complex internal and external behaviors of Effervescent atomizer are governing the behavior of the flow. The latter is a turbulent and compressible multiphase flow. It is studied numerically by employing a three-dimensional compressible Eulerian method along with Volume of Fluid (VOF) surface-tracking method coupled with the Large Eddy Simulation (LES) turbulence model. The numerical study is conducted by using OpenFoam library, an open-source package introduced by Open-CFD. In this study, the effect of varying the gas to liquid ratio (GLR) and the suspension (i.e. effect of viscosity, density and surface tension), on the structure of internal flow and consequently, the external flow is studied numerically. It is observed that the increase in GLR is accompanied with an evolution of the internal flow from a complex bubbly flow to an annular flow. This reduces the liquid film thickness at the discharge orifice. Further studies on internal pressure illustrated the critical condition, choked flow and pressure oscillations at the discharge orifice. The examination of increasing the GLR and evolving of internal flow resulted in changing in primary atomization parameters such as shortening the breakup length and widening the spray cone angle. Furthermore, the existence of a slip velocity between the two phases in the external flow results in dominant aerodynamic forces at high GLRs. Moreover, alternation of the liquid properties illustrated the higher spray velocity and wider cone angle of the spray, which demonstrates the superior performance of the Effervescent atomizer.

Book Synopsis Effervescent Atomization Through Circular and Elliptical Nozzles by : Sana Shaghaghian
Download or read book Effervescent Atomization Through Circular and Elliptical Nozzles written by Sana Shaghaghian and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effervescent atomization in quiescent air and in a subsonic crossflow are experimentally studied. The spray angle of an effervescent atomizer with an elliptical orifice is measured by employing the shadowgraph technique. Spray images were captured from both the minor and major axis views. The gas-liquid mass flow rate ratio (GLR) is in the range of 0.55-2.55 %. It is found that an increase in the aeration level results in an increase in the spray angle from both minor and major axis views. The results indicate that the spray angle from the minor axis view is wider than that from the major axis view and the difference increases as GLR rises. Furthermore, the effervescent atomization in a gaseous crossflow is studied using circular and elliptical orifices with aspect ratios of 1, 3, and 0.3. Gas-liquid mass flow rate ratio varies between (0-7%) and liquid-air momentum flux ratio,q, is in the range of 2-23. The high-speed shadowgraph technique and image processing were utilized to visualize the spray trajectory and measure the spray penetration height. Moreover, an empirical correlation is developed as a function of GLR, q, aspect ratio and downstream location. Additionally, the laser diffraction technique is employed to analyze the spray droplet size distribution in a crossflow.
