Dataset for: Point force singularities outside a drop covered with an incompressible surfactant: Image systems and their applications

This dataset contains analytical expressions for the: (i) mobility functions of two surfactant covered drops where one drop is much smaller than the other; and, (ii) velocity of a micro-organism (modeled as a Stokes dipole) outside a stationary clean and surfactant-laden drop. This dataset supports the manuscript: Shaik, V.A. & Ardekani, A.M. 2017. Point force singularities outside a drop covered with an incompressible surfactant: Image systems and their applications. Phys. Rev. Fluids, 2(11): 113606. doi: 10.1103/PhysRevFluids.2.113606 As the analytical expressions are too complicated to deduce the dependence of the aforementioned quantities on the viscosity ratio or the interfacial viscosity of the drops, we provide the data (by evaluating the analytical expressions) for: (a) increase in the speed of a small surfactant-laden drop (due to an external force acting on it) near a large force-free surfactant-laden drop; (b) velocity of a spherical micro-swimmer that is normal to the line joining the center of the swimmer and the surfactant-laden drop; and, (c) angular velocity of a spherical micro-swimmer outside a surfactant-laden-drop.
