PIV visualization of the surface. The velocity profile immediately reveals the linear velocity distribution in the center solid body rotation , a fixed layer of foam along the rim of the mug, and a narrow band of strong shear between those regions. The result is shown in the next figure. From Free Software Directory. The velocity data remains unchanged, but the value in the fifth column generally the peak height is set to

The series function of a digital compact camera is used to take two consecutive photos, as shown below. Dissolve your stack with 'Image - Stack - Stack to Images'. More examples Go to the users and publications forum for more examples.

Views Read View form View source View history. The image files are automatically saved in the same directory as the corresponding vector files. Stereo-PIV or even three components in space e.

Vector - remove invalid vectors set to zero Sets the value in the third and forth column to zero, when the value in the fifth column is negative or null.

The copyright and license notices on this page only apply to the text on this page. Deform shear interrogation windows Simple shearing of interrogation windows using affine transformation.

You are asked about a filename for the output. The source code documentation will be a good companion guiding you through the code. A more detailed explanation and some notes about the accuracy and sensitivity can be found in chapter 4.

For single pixel ensemble correlation, you need hundreds or even thousands of small images of a steady flow. This noise-insensitive method is especially useful for oversampled data, and structures that are large compared to the grid spacing. From Free Software Directory. At the moment, this function is only supported for double images. Check Only Sum Of Correlation if you prefer exporting only after all correlations are summed up.

Individual pre-shifts for following passes are taken from the previous passes, respectively.

You got the point - now we can start complaining, why this is rather a sloppy visualization and not a real PIV measurement: PIV in a cup of coffee. From the area of the profile you may derive a flow rate. Now, you can use a more convenient method for post processing.

JPIV introduction

The same image as above, after postprocessing. You can visualize the vorticity in the vector plots as a color coded background. In the "Settings" window, open the panel Vector Processing - Profile Extraction and modify the parameters.

Reference vector fields for comparison are included, as well as a data sheet with the synthetic image generation properties.

File - choose files Opens a file choser dialog. Use the PIVware tools script, to calculate the vorticity distribution of your flow field. Modify the properties on the panels in the "Settings" frame. Edit the interrogation window parameters. Select the filters you want to apply and how often they should be repeated. PIV ist mostly used for flow velocity measurements.

Select Color coding for the background and set the Data column to 4. A vector is considered to be invalid if its fifth column is negative or null.

Specify the upper left and the lower right corners of the region of interest in the text fields below. The velocity data remains unchanged, but the value in the fifth column generally ipiv peak height is set to -1 for invalid vectors.
