WebPhoresy or phoresis is a non-permanent commensalism-type interaction, where an organism (phoretic individual or phoront) attaches itself to another (host) for dispersion (Houck and O’Connor 1991). WebHere we present a simulation study of phoretic flow around a spherical colloid held fixed in a concentration gradient. We show that the resulting flow velocity depends non-monotonically on the strength of the colloid–fluid interaction.
