• 中文摘要： 本文經由實驗來探討液體中懸浮固體粒子對體積質傳係數(K/sub /L/A)之影響。實驗工作係研究攪拌槽內氧氣吸收於不同濃度及大小的玻璃珠及石灰石黏合液之情形。K/sub L/A之數值先隨著固體濃度之增加而遞減,然後又暫隨固體濃度之升高而增加。本文指出K/sub L/A 之減少,係因為A 值之減低,而K/sub L/A值之增加乃源自K/ sub L/數值之升高。本研究在不同溫度下進行實驗,也考慮了不同溫度下對氧氣擴散係數的影響。
• 英文摘要： The influence of suspended solid particles on the volumetric mass transfer coefficient in the liquid phase (K/ sub L/A) has been examined experimentally with the absorption of oxygen into slurries of various concentrations and sizes of glass beads and limestone particles using a stirred tank contactor. The value of K/sub L/A first decreases with an increase in solid concentration, and then locally increases in a certain range of the solid concentration. It is considered that the decrease in k/sub L/A is due to a decrease in the value of A and that the increase is mainly due to an increase in the value of k/sub L/. The effect of temperature is considered to be caused mainly by the difference in the diffusivities of oxygen at different temperatures employed in this study.
