Calculation procedure for conjugate viscous flows about and inside single bubbles
A numerical procedure is proposed to calculate conjugate viscous flows about and inside single bubbles.

Abstract
A numerical procedure is proposed to calculate conjugate viscous flows about and inside single bubbles. Using a body fitted mesh with multiblock and TVD-type treatment, conjugate flows on both sides of a bubble surface can be calculated. A “continuous stress method” is proposed to obtain interfacial velocities from the continuity of tangential stress.
Calculations are carried out for spherical bubbles in the range of and for deformable air bubbles rising in water in the ranges of . A comparison between the present conjugate model and Ryskin and Leal’s [1, 2] “external flow model” for a single bubble is made.

Additional Information:
The numerical simulation method proposed in this paper has high-fidelity of micro-flow details in the vicinity of a deformable bubble by guaranteeing the zero-thickness of a gas-liquid interface.
