rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...

Rotary atomizers are mainly used in agricultural manned aircrafts. Atomization characteristics at high speeds have been studied, but methods to measure the atomization efficiency not elucidated. The of rotary under high-speed airflow was investigated using an IEA-I wind tunnel experimental installation, AU5000 atomizer, and a laser diffraction particle size analyzer. Accordingly, model equation...

Wind tunnel measurements of drop size distributions from Micronair AU4000 and AU5000 rotary atomizers were collected to develop a database for model use. The measurements varied tank mix, flow rate, air speed, and blade angle conditions, which were correlated by multiple regressions (average R2 = 0.995 for AU4000 and 0.988 for AU5000). This database replaces an outdated set of rotary atomizer d...

Two of the important parameters in grinding operation are surface roughness of the workpiece and the amount of consumed energy. These parameters are strongly affected by the condition of grinding wheel surface which is dependent on the dressing parameters. Predicting the roughness of the grinding wheel surface after dressing with known dressing parameters can improve the grinding process. Resea...

. 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

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 paper describes the theoretical and experimental investigations of the key components and also the performance analysis of a rotary wheel for using as a solid desiccant dehumidifier and also indirect evaporator cooling system. Solid desiccants have long been used in dehumidification and cooling systems for energy efficiency or reduce electricity. Although many mathematical models on th...
