This is a 3D vector data set generated via a computational fluid dynamics simulator. The data is in ASCII format and represents one time slice of unsteady velocity in a turbulent channel flow. After a 2 line header, the rows of the file consist of 6 dimensions—x, y, z, u, v, and w. The dimensions are 96 by 65 by 48. The data set was provided by Drs. Jiacai Lu and Gretar Tryggvason, ME Department, Worcester Polytechnic Institute. Note, there is roughly a 20:1:1 ratio between u, v, and w.
