| Research Abstract |
In consideration of lubricated, acoustic and thermal properties in microbubbly fluid systems, efficient numerical solvers for the flow motion have been equipped. A numerical algorithm was developed to capture the flexibility in the biomaterial/membrane. For the microbubble dynamics, insight into several behaviors such as a lift force in a shear flow, a deformation mode in an acoustic field and a heat source due to the volume oscillation was gained. The simulation method was applied to predicting a microbubble heat enhancement in an ultrasound field, and confirmed to qualitatively reproduce the measured relation between the heated region and the void fraction.
