Combustion in swirling flows: A review
Combustion and Flame, 1974 Melting and burning of suspended alkane droplets are studied experimentally under electric field. It is found that the melting rate substantially decreases if electric field strength exceeds some critical value. It is about 60 kV/m under our experimental conditions.

Bubble elimination by swirl flow.
Hydraulics & Pneumatics, 1988 The performance of a newly developed bubble elimination system is analyzed. The system consists of a circular body for a swirled flow supplied tangentially, equiped with a throttle valve downward and a valve for discharging bubbles upward.A strong swirl superimposed on an averaged laminar flow during the initial state is found to decay exponentially ...
