Plots

This section shows some of the common plots used in the piston cooling simulation. The steps to create the plots are:

Fluid Model

The steps to create the plots in fluid model are:

1. Click Load Results in the Simulation Panel.
2. Select the result file piston_fluid_5760.sres in the ensuing Load Results dialog box, click Open.

Volume Fraction

The volume fraction is monitored with the volume fraction plots.

1. Select gallery under Volumes in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon, select Volume Fraction under Component oil in the Plot Panel.
4. Click Plot Selected Variables icon > click Plot Property icon.
5. In the Plot Property dialog box, enable Moving Average and enter 720.
6. Specify 0.45 for Maximum and 0.35 for Minimum under Display Default Range. Click OK.

Total Heat Flux

The total heat flux taken by the fluid from the solid is obtained as follows:

1. Select gallery_wall and piston_fluid_wall under Boundaries in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in the Plot Panel toolbar, select Total Flux in the MulticomponentHeat list.
4. Click Combine Entity Data into a Single Curve icon in the Plot Panel toolbar to obtain the net heat flux through the Boundaries.
5. Click Plot Property icon. In the Plot Property dialog box, enable Moving Average and enter 720.
6. Specify 0 W for Maximum and -12000 W for Minimum under Display Default Range. Click OK.

´	Note:  The above plot shows the heat flux that is mapped from fluid model to the solid model.

Solid Model

The steps to create the plots in Solid model are:

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

Total Heat Flux

The total heat flux taken by the fluid from the solid is obtained as follows:

1. Select piston_underside under Boundaries in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in the Plot Panel toolbar, select Total Flux in theHeat list.
4. Click Plot Selected Variables icon in the Plot Panel toolbar.
5. Click Plot Property icon. In the Plot Property dialog box, specify 4000 W for Maximum and -1500 W for Minimum under Display Default Range. Click OK.

Temperature

The temperature is plotted at the monitoring points as follows:

1. Select crown_center, topland_inletside and topland_outletside under Points in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in the Plot Panel toolbar, select Temperature in the Heat list.
4. Click Plot Selected Variables icon in the Plot Panel toolbar.
