The shape oscillation of an encapsulated microbubble in an ultrasound field is numerically investigated. To predict the nonlinear process, the continuity equation and the Navier-Stokes equation are directly solved by means of a boundary-fitted finite-volume method on an orthogonal curvilinear coordi...
