This work is focused on a single bubbling from orifice at the plate as the first step for modelling of multi-orifice bubble formation at perforated plate. We explored experimentally an influence of design parameters (orifice diameter, plate thickness, liquid viscosity, gas chamber volume) on the interphase meniscus behaviour. The influence of an external acoustic field on the meniscus and bubble formation was explored also to simulate an influence of the sound field produced by other bubbles in real process. Acquired characteristics of the meniscus were incorporated into the model of bubble formation process.
