29.10.3 Displaying Turbomachinery Averaged Contours

Turbo averaged contours are generated as projections of the values of a variable averaged in the circumferential direction and visualized on an $r$- $z$ plane. A sample plot is shown in Figure  29.10.7.

Steps for Generating Turbomachinery Averaged Contour Plots

You can display contours using the Turbo Averaged Contours dialog box (Figure  29.10.6).

Figure 29.10.6: The Turbo Averaged Contours Dialog Box

The basic steps for generating a turbo averaged contour plot are as follows:

1.   Select All or a specific predefined turbomachinery topology from the Turbo Topology drop-down list.

2.   Select the variable or function to be displayed in the Contours of drop-down list. First select the desired category in the upper list; you may then select a related quantity in the lower list. (See Section  29.10.7 for a list of turbomachinery-specific variables, and see Chapter  31 for an explanation of the variables in the list.)

3.   Specify the number of contours in the Levels field. The maximum number of levels allowed is 100.

4.   Set any of the options described below.

5.   Click the Display button to draw the specified contours in the active graphics window.

The resulting display will include the specified number of contours of the selected variable, with the magnitude on each one determined by equally incrementing between the values shown in the Min and Max fields.

Note that the Min and Max values displayed in the dialog box are the minimum and maximum averaged values. These limits will in general be different from the global Domain Min and Domain Max, which are also displayed for your reference (see Figure  29.10.6).

Contour Plot Options

The options mentioned in the procedure above include drawing color-filled contours (instead of line contours), specifying a range of values to be contoured, and storing the contour plot settings. These options are the same as those in the standard Contours dialog box. See Section  29.1.2 for details about using them.
