Scaling of Lift Reversal of Deformed Bubbles in Air-Water Systems
Hayashi, K.; Heßenkemper, H.; Lucas, D.; Legendre, D.; Tomiyama, A.
Scaling of the lift reversal for a deformed bubble in the surface tension-inertial force dominant regime was discussed. Lift data of bubbles in water recently reported in literature were used. The negative lift component was well correlated in terms of the drag coefficient, which, in turn, implies that the vorticity produced at the bubble surface plays a key role in both drag and lift forces as is the case with the viscous force dominant regime. The scaling was confirmed to give good evaluations of the lift coefficients.
