CFD modeling of primary breakup during metal powder atomization

A Comprehensive Review on Fluid Dynamics and Transport of Suspension/Liquid Droplets and Particles in High-Velocity Oxygen-Fuel (HVOF) Thermal Spray

“… Mass conservation  Handling flows with large density ratios (liquid-to-gas ratio)  Accurate interface representation and advection  Spurious currents Among the mentioned interface tracking/capturing methods, volume of fluid (VOF) is widely used to simulate the primary atomization [207,[226][227][228][229][230][231][232][233][234]. Moreover, the pros and cons of this method are extensively studied based on the mentioned four issues [208,225].…”

The identification of an accurate simulation approach to predict the effect of operational parameters on the particle size distribution (PSD) of powders produced by an industrial close-coupled gas atomiser

“…Close-coupled gas atomisation involves the molten metal stream being delivered into the atomising gas via a ceramic melt delivery tube, and is the most commonly utilised configuration by industry [4,5]. Figure 1 provides a simplified schematic of the close-coupled configuration; it should be noted that the length of the melt delivery tube is a critical parameter in the performance of the atomiser, as has been shown by Mi et al [6].…”

CFD modeling and its validation of non-Newtonian fluid flow in a microparticle production process using fan jet nozzles

“…Atomization is a well-known technique that has been used for some time in a number of applications such as the feed of fuel into internal combustion engines [1][2][3], spray drying in the food and consumer goods industry [4][5][6], coating of surfaces [7,8], energy and atmospheric studies and more recently for evaluating the performance of nasal spray devices [9][10][11]. It can be differentiated between one-fluid atomization and two-fluid atomization.…”
