| Abstract: | In order to study the influence of the geometric similarity scale factor of the water model on the mixing time, the physical simulation experiments were carried out with the plexiglass water model with the geometric similarity scale of 1/4.5, 1/7.4, 1/10 and 1/17.3, respectively. The mixing time of the fluid in the ladle model under different conditions was measured by the conductivity meter. The results showed that the geometric similarity scale factor of the model has an effect on the exponential n of the fitting curve between the mixing power and the mixing time. With the increase of the model scale, the absolute value of the n gradually decreased. When the model scale was less than 1/7.4, the n changed greatly, and the slope of the fitting line of the n was -3.97; when the model scale was greater than 1/7.4, the n changed little, and the slope of the fitting line of the n was -0.19. At the same time, for central and eccentric blowing, the change range of n was also different. When central blowing, the change range of n was 0.25-0.75; when eccentric blowing, the change range of n was 0.30-0.60. |
