We focus on the dynamic particle accumulation structure (PAS) due to the thermocapillary effect in a half-zone liquid bridge. In this study, by tracking particles in the liquid bridge and by measuring temperature on the free surface, we discuss the effects of a liquid bridge shape described by its volume ratio upon the shape of the PAS itself and motion of particle on the PAS. The variation of the liquid bridge volume ratio leads to a significant variation of the temperature gradient on the free surface, which results in difference of the shape of the PAS, especially width of the PAS blade. By considering the simply modeled particle motion, we explain that the width of the PAS blade is determined by several parameters, and we find that its variation is explained mainly by a drastic change of the axial velocity of the particle on the surface.
