“…The velocity vectors, on the cross-section of z = 0.5 for the thermocapillary flow, as shown in Figure 7, are similar to those for low Reynolds number lid-driven cavity flow. However, as shown in Figure 8, the velocity vector on the cross-section of y =0.5 are totally different from those for lid-driven cavity flows [14]. The temperature contours become more tortuous with time, as shown in It should be mentioned that the vortices at the corners of the free surface for Re= 100 and Pr =1.0 are not observed in the work by Babu and Korpela [8].…”
