Velocity fields from turbulence tanks, with analysis performed to describe its turbulence characteristics analyzed at University of California - Berkeley (DiatomTrajectories project)

<p>This dataset is available as a large.zip file (1.8 GB compressed; 3.5 GB uncompressed) available for <a href=\"http://dmoserv3.bco-dmo.org/data/DiatomTrajectories/Final_Turbulence_analysis.zip\">Download</a> (WARNING: LARGE FILE). Each folder represents a different experiment. In the folders are:</p>

<p>1) A series of txt files, each of which describes 1 independent sample of a 3D velocity vector field measured in an x-y plane in the turbulence tank. The data is 5-column tab-delimited data:<br />
Column 1 is x-location of velocity measurement (in mm, and defined relative to origin at the tank’s geometric center)<br />
Column 2 is y-location (in mm)<br />
Column 3 is x-component of velocity vector (in m/s)<br />
Column 4 and 5 are y- and z-components of velocity vector, respectively (in m/s)</p>

<p>2) A *.mat file, including the same data as above, but arranged into an LxMxN matrix, in which L is x-location, M is y-location, and N is number of independent samples.&nbsp; Velocity components are called UU,VV, and WW.&nbsp; The x- and y- values are called xvals and yvals.&nbsp; This file is constructed from the *.txt files using the *.m file found in the root directory “view_and_organize_vectors_from_Darling.m”</p>

<p>3) Eight *.png figures that summarize the turbulent features of velocity fields.</p>

<p>4) A *.dat file giving some key statistics describing the turbulent features of velocity fields.&nbsp; This file is constructed from the *.mat files using the *.m file found in the root directory “analyze_vectors_from_Darling.m”</p>
