MPS陽解法による高粘性ニュートン流体攪拌トルクの数値解析

Numerical simulation was conducted in this study to calculate the agitating torque of high viscosity Newtonian fluid by explicit-MPS method using virtual boundary particles for container and flapper. At first, a calculation resting hydraulic pressure carried out confirm vicinity As result, it confirmed that average distribution corresponded with theoretical value pressure. Considering trial flapper calculated from rotated The caused differential between front back faces shear stress particle near edges. From calculation, stable torques were obtained each time step at speed, consistent viscous test results which showed linear relationship number speed agitation torque. Furthermore, dominated
