Plots

This section shows some of the common plots used in the gerotor 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 160, click OK.
5. Click Combine Entity Data into a Single Curve to obtain the net mass flux.

Pressure

The pressure ripples are monitored at the monitoring points outlet_top and outlet_bot. They are obtained as follows:

1. Select outlet_top and outlet_bot under Points 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 Pressure from Flow list.
4. Click Plot Selected Variables icon.

Power

The instantaneous integrated power about the axis of rotation for the inner, outer rotor or rotating port is plotted. The power is computed based on the instantaneous integrated torque and the rotation speed.

To create the plot for the revolution average power:

1. Select inner_rotor and outer_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 Gerotor list.
4. Click Combine Entity Data into a Single Curve icon in the bottom left of Plot Panel, to obtain the net power.
