Abstract The chemically active droplets, which converts the chemical energy into a localized fluid flow at the
interfaces by generating a concentration gradients of surfactant, can realize self-propulsion with complex
trajectories and have been widely studied to mimic the swimming behavior of micro-organisms. In
reality, the motion of chemically active droplets is influenced by a combination of diffusiophoresis and
Marangoni effect under concentration gradients of surfactant. However, the interaction between these
two effects has been only studied for a drop under the constraint of the axial-symmetric motion. To
understand the hydrodynamics of the unconstraint motion, we consider a two-dimensional drop model… More >
