In our previously proposed concept of sedimentation turbulence, the feed-forward mechanism of flocculation induced by a sequential cohesive collision between settling flocs during the sedimentation process resulted in the monotonous increase of the settling velocity with increments of the settling cylinder height. However, the monotonous increase of the settling velocity and the size of flocs onset of the sedimentation turbulence are considered to meet across their limiting values. In order to confirm this conjecture, the effects of container sizes, i.e., the diameter and the height of the settling cylinder, on the validity of this concept were investigated on the basis of maximum floc size, which was maintained during the sedimentation process. The sedimentation experiments of highly coagulated Na-montmorillonite in the semi-dilute regime were extended using cylinders taller in height and smaller in diameter. The results obtained demonstrate that the maximum velocity becomes much faster than that of the free settling of a single floc. A notable observation was made when a cylinder with a diameter of 10 mm was used and in which the corresponding floc size was in the same order of magnitude. In this case, the clogged large floc essentially stopped its sedimentation motion. The crude estimation of the fluid force exerted on the floc during the sedimentation process was found to be consistent with this drastic change.

在我们之前提出的沉降湍流概念中，沉降过程中沉降絮体之间的连续内聚碰撞引起的絮凝前馈机制导致沉降速度随着沉降筒高度的增加而单调增加。然而，沉降速度的单调增加和沉降湍流开始的絮体大小被认为满足了它们的极限值。为了证实这一猜想，在沉降过程中保持的最大絮凝体尺寸的基础上，研究了容器尺寸（即沉降筒的直径和高度）对这一概念有效性的影响。使用高度更高和直径更小的圆柱体扩展了半稀释状态下高度凝聚的Na-蒙脱石的沉降实验。获得的结果表明，最大速度比单个絮体的自由沉降速度快得多。当使用直径为 10 毫米的圆柱体并且其中相应的絮体大小处于相同数量级时，进行了显着观察。在这种情况下，堵塞的大絮团基本上停止了其沉降运动。发现在沉降过程中对絮体施加的流体力的粗略估计与这种剧烈变化是一致的。获得的结果表明，最大速度比单个絮体的自由沉降速度快得多。当使用直径为 10 毫米的圆柱体并且其中相应的絮体大小处于相同数量级时，进行了显着观察。在这种情况下，堵塞的大絮团基本上停止了其沉降运动。发现在沉降过程中对絮体施加的流体力的粗略估计与这种剧烈变化是一致的。获得的结果表明，最大速度比单个絮体的自由沉降速度快得多。当使用直径为 10 毫米的圆柱体并且其中相应的絮体大小处于相同数量级时，进行了显着观察。在这种情况下，堵塞的大絮团基本上停止了其沉降运动。发现在沉降过程中对絮体施加的流体力的粗略估计与这种剧烈变化是一致的。
