Abstract The distribution of surface tension on the front and rear sides a camphor boat continuously moving an aqueous-phase solution was observed by time-resolved quasi-elastic laser scattering method. uniform motion induced difference in between sides. A surface-tension gradient developed along side, resulting Marangoni convection that decelerated boat.
