Tank Parts
The Mixer Module Part Library includes three different cylindrical tanks: a dished bottom tank, a flat bottom tank, and a cone bottom tank. The three tank types are shown in Figure 2-2 below.
Figure 2-2: Tank parts available in the Mixer Module Part Library.
All tank parts can be defined to include an optional number of baffles in order to improve mixing. Baffles are specially required when radial impellers are used, in order to avoid a near solid body rotation of the fluid.
By default, the tank’s cylindrical part is positioned with its base at z = 0. This implies that the dished and cone bottom sections are positioned just below the xy-plane. If you define a flat bottom tank with a fillet radius on the lower cylinder edge, then also the fillet section created is placed just below the xy-plane. If you specify a zero fillet radius for a flat bottom tank, then the base of the tank is positioned in the xy-plane, that is, at z = 0.
The impeller shaft’s lowest part is also by default positioned at z = 0. You can change the position, length, and diameter of the impeller shaft. However, the impeller shaft is always placed in the middle of the tank perpendicular to the xy-plane.
