WebMar 14, 2014 · Abstract Phoretic self-propulsion is a unique example of force- and torque-free motion on small scales. The classical framework describing the flow field around a particle swimming by self-diffusiophoresis neglects the advection of the solute field by the flow and assumes that the chemical interaction layer is thin compared to the particle size. … WebThe study of the phoretic plane thus provides a framework to understand the motion of the phoretic particle. Many questions remain open. For example, how does the particle motion and flow field change for phoretic particles in a complicated environment, such as phoretic particle near a wall?
