IntroductionThis fluid dynamics video shows the evolution of the flow over a golf ball from different several perspectives in space. The variables shown in the video are isosurfaces of the Q-criterion [1] colored by spanwise vorticity, contours of spanwise vorticity, and an isosurface of the vorticity magnitude.The first section of the video presents an isosurface of the Q-criterion colored by

Q criterion isosurface

Isosurface The `Isosurface' representation computes and draws a surface within a volumetric data field, on a 3-D surface corresponding to points with a single scalar value. There are several settings which control how the isosurface is displayed. Isosurface An isosurface is a 3D surface representation of points with equal values in a 3D data distribution. Is the 3D equivalent of a contour line. An isosurface can be used to represent, for example, all VoXels in an image with a given CoLocalization level.

Calculate Q-Criterion with Tecplot 360. In this video we’ll show you how to calculate Q-Criterion, plot the results, and compare the performance of Plot3D and SZL file formats for this work.

From the series: Isosurface of Q-criterion and streamlines in the right cavity on the left and Iso- surface of Q-criterion of the nasopharynx region on the right (time=0.2s). These figures were obtained by averaging flow field over one shaft revolution. Figure 4.

Then, when creating a 4D isosurface for f = 0 in the time range of [0, 1], the isosurface will go through all the points a < f(x, y, z) < b at time-steps between 0 and 1. If we perform a parallel projection of the 4D isosurface along the (0,0,0,1) direction, triangulation of the interval volume can be successfully obtained.

The video shows the effect of active surface morphing on the flow transition exhibited in a shock wave boundary layer interaction, in terms of Q criterion isosurface, completely eliminating the flow separation and transition. The vertical axis is scaled for clarity. The Q criterion is written as Q = 0.5* (vorticity 2 - strain rate 2) > 0 meaning relative dominance of the rotational component over the stretching component in deformation of a fluid element. Fig. 25 shows the Q-isosurface of the whole configuration under AoA of 16° at t = 0.1 s, where the threshold value of Q is 100. As can be seen, under the same Q criterion, the isosurface of the design configuration is smaller than that of the baseline configuration, which is because the flow separations are weakened by the design configuration.

The Q value is defined as the relative difference between the mag This can be leveraged to effectively define an isosurface of Q-criterion to extract the coherent vortical structures. Shown below is the resulting visualization colored by vorticity magnitude for Q = 0.01. These isosurfaces of Q-criterion clearly illustrate the rotor wake and the swirl caused by the rotation as the wake convects downstream. Q-criterion isosurfaces in MATLAB Posted July 1, 2013 at 11:33 by sbaffini Updated %Plotting a Q isosurface, Q=iso_q figure() p=patch(isosurface(x,y,z,q,iso_q)); The isosurface of Q-criterion you should plot is "some positive number that you like" Q-criterion is also dimensional in its pure definition, so one type of flow you take Q=1 and another type of flow you might take Q = 1000.
