在不同几何形状、不同入口直径和不同操作条件（颗粒直径、静止床层高度和空气流速）下，用光纤探针测定了锥形喷动床的局部空隙率。根据实验结果，提出并验证了计算沿喷动轴线沿着和接触器壁附近床层空隙率的原始关联式。提出了一种计算任意床层位置处床层空隙率的关联式，该关联式是沿喷动轴沿着和壁面处床层空隙率以及喷动半径的函数。
Local bed voidages have been experimentally determined by means of an optical fiber probe in conical spouted beds of different geometry tangle, inlet diameter) and working under different operating conditions (particle diameter, stagnant bed height, and air velocity). Based on the experimental results, original correlations have been proposed and proven for calculation of bed voidage along the axis of the spout and near the contactor wall. A correlation has been proposed for calculation of bed voidage at any bed position as a function both of bed voidage along the spout axis and at the wall and of the spout radius.
