Internal Flow Analysis of a Slinger Atomizer
Ali Charanandeh,Yechan Seo,Jeekeun Lee 대한기계학회 2021 대한기계학회 춘추학술대회 Vol.2021 No.11
In the present experimental and computational study, the internal flow of a Slinger atomizer is investigated. A nozzle with an outer glass disk was designed to visually scrutinize the nozzle internal flow, and numerical simulations were conducted using the Volume of Fluid (VOF) model to discern the interface between two phases. Both CFD simulations and experimental visualizations revealed that, contrary to current assumptions, the liquid flow distribution inside the slinger nozzle is not uniform. It was observed that gravity has a significant impact on the internal flow of the nozzle and is one of the primary causes of the slinger atomizers non-uniform flow distribution. Also, liquid non-uniformity was observed inside the nozzle orifices.
