高レイノルズ数じゃま板付きかくはん槽内流れの数値シミュレーションと実験による検証
Unsteady flow in a baffled stirred tank of which Reynolds number based on the tip velocity and the radius of tank is 45000 has been simulated by solving numerically Navier-Stokes and continuity equations. LES model were used for sub-grid scale flows. Calculated results show unsteady flow fields in the whole region of the tank during about 16 complete impeller revolutions. As the results we present the occurrence and the disruption of large vortices, and the generation of many small eddies which
