A numerical study of airflow and spray transport from rotary cup atomizer using KIVA-3V is carried out. The numerical result show that the electrostatic field speed up spray droplet speed and improve transfer efficiency. Breakup model produces smaller drops which are entrained into the center recirculation zone. The results of a parametric study considering different cup rotational speed, shapi...

This study of effervescent atomization, a two-phase gas-liquid spray generation technique that offers many advantages over conventional atomizers, shows the advantage streamlined aerator design flat-end type with respect to formation gas-void in wake interior an inside-out atomizer. The experiments use high-speed shadowgraphy visualizations. It is observed that, design, undesirable and leads ch...

. A technique for hydrodynamic experiments has been developed to study a disk atomizer in rotary mass transfer apparatus. In the course of experiments, indicator method determines average residence time liquid on contact device, volume retained diameter droplets formed, and height gas-liquid layer

Background: currently, functional foods are the type of foods of most interest to the modern consumer, due to the health benefits they provide. Objectives: Optimize the spray drying process to obtain cape gooseberry powder added with active compounds. Methods: A process of spray drying was carried out to obtain a powder from cape gooseberry suspensions added with vitamin C, iron, folic acid, is...

Effervescent atomizer produced sprays were studied for application to rotary kiln incinerators. The sprays were characterized by their number averaged droplet velocity profiles, Sauter mean diameter (SMD) profiles, and size-velocity correlations. Spray mass flow rates ranged from 30 to 120 g/s. Air-liquid-ratios by mass (ALRs) were between 2% and 10%. Data were obtained at seven to ten radial p...

The analysis of solutions containing appreciable amounts of dissolved solids by flame atomic absorption requires careful consideration of the solution chemistry and sample preparation as well as an informed choice of instrumental operating conditions in order to obtain reliable results. A common problem is the physical obstruction of parts of the flame atomizer by salt accumulation which leads ...
