The purpose of this study is to understand the shear rate of cooling water and silicone oil when they are stirred by up-and-down motion. For this purpose, an experiment and simulations using a Moving Particle Semi-implicit (MPS) method were conducted. The stirring experiment was performed under the same condition as in the simulation, and the validity of the simulation was examined by comparing the results. The liquid surface deformation was observed in the experiment, and it was confirmed that the behavior expressed in the simulation was in good agreement with the experimental one. The simulations were performed at three different velocity of reciprocating motion of 0.04m/s, 0.07m/s, and 0.1m/s, and the shear rates in each case were compared and discussed. As a result, the relationship between the velocity of reciprocating motion and the shear rate, and the relationship between the up-and-down motion and the shear rate were clarified.
