Abstract
Equations were derived for the prediction of the drag coefficient of a collapsing bubble during its flow in liquid. Expressions were obtained analytically for the drag coefficient in terms of Reynolds, Peclet, and Jakob numbers as well as a dimensionless time for the collapse of a thermally controlled bubble. Equations were derived for the drag coefficient and virtual mass coefficient for a collapsing bubble under inertia-controlled and mass-diffusion-controlled processes. The flow and thermal parameters were obtained by solving the viscous dissipation integral around the bubble surface. These new theoretical results showed agreement with previously reported numerical solutions and experimental data. Some avenues for further research were pointed out.
