摘要：In this talk, we investigate the equation governing the movement of an immersed interface in incompressible fluid flows, and propose efficient methods for its numerical solutions.The particularity of the model is the inextensibility constraint imposed on the interface.We are interested in constructing suitable variational formulations associated to this problem and the well-posedness of the weak problem.The significance of this variational formulation is that both the Inextensibility of the interface and fluid incompressibility are strictly satisfied, so thatwell-posedness of the associated weak problem can be rigorously established.Then, based on the proposed variational framework,we design efficient methods for numerical approximations to the weak solution, together with a detailed stability analysis.
