Evaluation of Orifice Shape Design on Flat Fan Atomization

The atomizer is a crucial component in spray columns used in mass transfer applications. Proper function of the atomizer can enhance mass transfer and reduce sorbent evaporation and droplet drift (physical loss). Commonly used atomizers for spray column application suffer from excessive droplet drift and high spray polydispersity. Flat fan sprays were beneficially used to reduce droplet drift in agricultural applications and in studies dealing with CO2 capture. Six 3D printed flat fan atomizers with different internal channel geometry (elliptical, cone-shaped) were tested at four inlet pressures in this study. The liquid sheet breakup length and spray cone angle derived from high-speed visualization are compared for each atomizer design. No systematic difference was found between the elliptical and cone-shaped channels. The spray cone angle and breakup length were corelated only with experimental regimes (Reynolds number and Weber number). Perforations were responsible for the breakup of the liquid sheet at lower injection pressures, whereas the combined effect of perforations and waves dominated the liquid sheet breakup at higher injection pressures.
