Plots

This section shows some of the common plots used in the progressive cavity pump simulation. The steps to create the plots are:

1. Click Load Results in the Simulation Panel.
2. Select the required result file in the ensuing Load Results dialog box, click Open.

Mass Flux

The mass balance is monitored with the mass flux plots.

1. Select inlet_inlet and outlet_outlet under Boundaries in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon, select Mass Flux under Flow in the Plot Panel.
4. Select Plot Selected Variables icon > click Plot Property icon. In the Plot Property dialog box enable Moving Average and enter 180.
5. Specify 0.2 kg/s for Maximum and -0.2 kg/s for Minimum under Display Default Range. Click OK.
6. Click Combine Entity Data into a Single Curve to obtain the net mass flux.

Flow Rate

The flow rate is monitored at the outlet boundary. They are obtained as follows:

1. Select outlet_outlet from the Boundaries list in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in Plot Panel toolbar, select Revolution Average Volumetric Flux from Progressive list.
4. Click Plot Selected Variables icon.
5. Select Plot Property icon. In the Plot Property dialog box, select L/min for Units and specify 10 L/min for Maximum and -10 L/min for Minimum under Display Default Range. Click OK.

Power

The instantaneous integrated power about the axis of rotation for the rotor is plotted. The power is computed based on the instantaneous integrated torque and the rotation speed.

To create the plot for the power:

1. Select rotor under Boundariesin the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. In the Plot Panel, select Revolution Average Power for Progressive list.
4. Click Plot Selected Variables icon.
