Abstract

Utilizing the recent analytical result, we numerically study the drag coefficient of a circular liquid domain in a flat fluid membrane, surrounded by three-dimensional fluids. Its derivative with respect to the domain viscosity is evaluated when the domain viscosity is the same as the membrane viscosity outside the domain. We show that the drag coefficient is smaller when the domain is more viscous, unlike that of a liquid droplet in a three-dimensional fluid.
