Learn how to predict mixing in a tank filled with two fluids and a rotating agitator. To setup this CFD analysis a rotating region is specified using the "sliding" mesh approach, and two different liquids are initialized in the tank. A time-dependent or "transient" analysis is run and result cut plots are created and animated versus time. The torque on the agitator is also extracted.
Key Observations:
The torque decreases as the X-values increase (from 1105.3 at the lowest X-value to 398.7 at a higher X-value). This is typical in mixing systems where torque often drops with increasing speed due to fluid dynamics (e.g., reduced viscous resistance at higher Reynolds numbers).
The values 1,000 to 6,000 could represent a sweep of operational speeds, with the "(x)" points marking actual simulated data points.
Possible Conclusions from CFD Analysis:
The agitator requires higher torque at lower speeds (e.g., startup) but less torque at higher speeds.
The simulation may aim to identify optimal operating conditions (e.g., balancing torque and mixing efficiency).
