摘要：
The quantitative formula of infiltration flux during titanium alloy melt feeding in centrifugal field was deducted. The infiltration flow mechanism in centrifugal field was analyzed. Based on the formula of infiltration flux and the similar physical simulation theory, the similarity criterion was presented. The results show that, the deduction of the formula of infiltration flux during titanium alloy melt feeding in centrifugal field can be divided into four stages in terms of Reynolds number, that is low-speed infiltration, Darcy infiltration, transient zone infiltration and high-speed infiltration. The feeding infiltration fluxes at four stages increase with increasing of rotation speed and centrifugal radius. The viscosity ratio of the model fluid to the titanium alloy melt is 0.365.
