Conditional sampling schemes based on the Variable Interval Time Averaging (VITA) algorithm
Abstract
The variable interval time averaging (VITA) algorithm was tested in a variety of boundary layers for its ability to detect motions principally involved in the production of shear stress. A VITA+LEVEL scheme (which uses a variance and level criterion) was devised and is shown to produce length scale statistics that are independent of the conditioning criteria, where those from the VITA scheme are not.
