| 概要 | The electromagnetically spinning method for viscosity measurement was enhanced for applications in a confined reaction chamber. In the reaction chamber, the immersion of the rotor into the sample might trigger the precipitation and aggregation of ingredients to the pivot of the probe rotor, which leads to harmful frictional torque of the rotation. To address this problem, an upper-point-type auto-standing probe rotor was developed and applied for the long-term measurement of the solution process of rock sugar in water. In addition, we propose the adoption of a punched board, instead of a solid board, as the lower substrate of the plate-plate-type rotational viscometer, which allows rapid exchange of the sample fluid between the interior and exterior of the narrow measurement area through molecular diffusion. We investigated the effect of punches from the perspective of the diffusion process of momentum and determined the geometrical conditions. |
