Effervescent atomizer: influence of the internal geometry on atomization performance
Our work is being conducted with the aim to develop an effervescent atomizer for industrial burners that will generate a fine and stable spray in large turn-down ratio. The single-hole, plain orifice atomizer is powered with light heating oil and uses air as an atomizing medium in the “outside-in” gas injection configuration. Published design concepts of the effervescent atomizer are described....
متن کاملInfluence of Geometry on the Performance of Simplex Nozzles under Constant Pressure Drop
In this paper, the effect of atomizer geometry on the flow in simplex atomizers and atomizer performance is numerically investigated. A computational model based on the Arbitrary-Lagrangian-Eulerian method has been used. The effect of changes in four non-dimensional geometric parameters on the atomizer performance is studied. These geometric parameters are the atomizer constant (ratio of inlet ...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Numerical Simulation of Internal Flow in a Large-scale Pressure-swirl Atomizer
This work is a continuation of experimental and computational studies of the internal flow field of a large-scale Danfoss atomizer presented at an earlier ILASS conference [1,2]. Fluent 6.1 is used to simulate the flow through the large-scale atomizer. The two-phase flow is modeled using three approaches: 1) a volume of fluid (VOF) method using a laminar flow assumption, 2) a VOF method using l...
متن کاملSpray Characteristics of a Liquid-Liquid Coaxial Swirl Atomizer at Different Mass Flux Ratios
An experimental investigation is performed to explore the characteristics of sprays produced by a liquid-liquid coaxial swirl injector in a non-combusting environment. Phase Doppler anemometry is used for the measurement of velocity and Sauter mean diameter of droplets across and along the injection axis for various innerand outer mass flow rates. Results of the combined spray are compared with...
