Plot gallery

This page shows each static plot of vane.viz at the two printed sizes, one journal column (size="single", 8.5 cm wide) and the full page width (size="double", 17 cm). The figures follow the style and encoding described in Visualization: the lab’s standard line colours, mode families by colour (blades green, tower black, platform red, drivetrain magenta, other modes cyan), line styles cycling within a family, multi-blade types by marker, and blue nP lines tagged inline.

The images are generated from synthetic data by the script docs/gallery/make_gallery.py in the source repository, which writes a sweep of the synthetic turbine of the tutorials (tower, rotor and blade-flap modes, 4 to 11 m/s) and analyses it with run_study(). They are shown here as PNG files at 150 dpi; for a paper, write the same figures as vector PDF or SVG with save_figure(). Each section gives the call that draws the figure.

Campbell diagram

The frequencies of the tracked modes against rotor speed, with the 1P, 3P and 6P lines and the resonance crossings. Each mode is named at its line end; in the single-column figure the names are shortened.

Campbell diagram with every mode family

A hand-built floating-turbine diagram that uses every family, a low-confidence track (faded), an ambiguous track (open diamonds) and a shaded operating window.

    diagram, harmonics=(1, 3, 6), operating_range=(6.9, 12.1), size="double"
)

Damping ratio

The damping ratio of each track, with the unstable region (below zero) and the low-margin caution band shaded.

plot_damping_static(diagram, size="single")

Frequency and damping panels

The Campbell diagram (a) and the damping ratio (b) on a shared rotor-speed axis, stacked at single-column width and side by side at double-column width.

Mode participation

The signed participation of the most active degrees of freedom of the regressive blade-flap mode at 8 m/s.

plot_mode_participation(
    solution, mode_index, top_n=5, short_names=True, size="single"
)

Phasor wheel

The same mode’s degrees of freedom as phasors: the cosine and sine flap coordinates a quarter period apart, the signature of a whirling mode.

Multi-blade components

How the mode’s participation divides among the collective, cosine and sine coordinates.

plot_blade_components_static(solution, mode_index, size="single")

Complex mode shape in 3-D

Each degree of freedom as a stem to its complex component.

plot_mode_3d_static(solution, mode_index, top_n=5, size="single")

Whole-turbine mode shape

A coupled platform-pitch, tower and flap mode of a floating turbine drawn on the schematic semi-submersible geometry; the grey outline is the undeformed structure.

plot_mode_fowt_static(solution, mode_index, size="single")

MAC matrix

The modal assurance criterion between the modes of two adjacent operating points; the diagonal shows that every mode tracks cleanly.

plot_mac_matrix_static(solutions[3], solutions[4], size="single")

Tracking confidence

The identification confidence of each track of the floating-turbine diagram, with the ambiguous track in orange and the review threshold dashed.

plot_tracking_confidence_static(diagram, size="single")

Azimuth coverage

The twelve azimuths sampled at each operating point of the study.

plot_azimuth_coverage_static(study.provenance, size="single")

Branch review

A crossing of two modes found by the branch review, with the closest approach marked.

plot_branch_review_static(diagram, result.branch_groups, size="double")

Load-versus-mode map

The normalized contribution of each mode to each load output of the synthetic turbine (tower-base and blade-root moments).
