- 論文の詳細を見る
A method to determine the expression coefficient is developed employing a weighted residual method, and is successfully applied to the expression of a slurry of titanium dioxide in water. It is found that the expression coefficient, which has been reported to be dependent on the void ratio, is also strongly dependent on the initial void ratio of the slurry, ranging from 1.86 to 3.30 in the present study. The basic equation of the expression process with a Lagrangian variable is analyzed, using the experimentally determined coefficient. A finite difference method and a moment method are used to solve the basic equation. The expression ratio is computed and compared with experimental results, with excellent agreement.
