The effects of stir velocity, slurry viscosity and density on the porosity were studied and the porosity was characterized by using the Reynolds number according to the bubble forming theory in this paper. It is found that the porosity is the same if the Reynolds number is the same regardless different stir velocity, slurry viscosity or slurry density. The quantitative functional relationships between the porosity and Reynolds number was deduced.
