Abstract

The creation of sequential droplets that fall through a vertical string at a specific period without any clash and maintaining the same pace is an ideal condition for any heat/mass transfer calculation as the entire system can be deemed stagnant. The available investigations to create those sequential droplets on vertical string mainly focus on flow rate and nozzle diameter. Contrary to prior studies, this investigation focuses on the effect of the nozzle tip geometry on droplet generation along vertical string while keeping constant flow rate and nozzle diameter. The nozzle tip geometry has been modified to form different droplet diameters while considering the fundamentals of droplet generation. The changes in droplet diameters, which flow down the vertical string for each specific nozzle tip geometry, were investigated experimentally. All results and findings have been presented in this paper.
