Original Abstract
A novel method is presented to quantify the unsteadiness of effervescent atomizer generated spray in relation to operational conditions and two-phase flow pattern inside the atomizer mixing chamber. The method, derived and applied here, is based on the measurement of pressure fluctuations in the atomizer mixing chamber. The results show steady spray behaviour at higher GLRs, where the atomizer is operated in dispersed or annular regimes of the internal two-phase flow. Decrease of GLR to below 6%, where non-uniform internal two phase flow appears, leads to unsteady spray.
