Three dimensional 'oscillatory' convection appears in a half-zone liquid bridge of a high Prandtl number fluid (Pr > 10) when a temperature difference between both end surfaces of the bridge exceeds a critical value. In the present study, flow patterns induced by thermocapillary-driven convection far from the criticality are obtained by numerical simulation. The flow patterns are distinguished through the velocity and temperature variation in the bridge, the power spectrum of the surface temperature variation, the reconstructed pseudo-phase space and the evaluations of the correlation dimension and the Lyapunov exponents. The reconstructed flow patterns and their characteristics are in good agreement with the experimental results by our group.
