Resolution Effects in Chaotic Velocity Field Reconstruction from Passive Scalar Data

A study uses the subsets of the scalar grid function that were generated as the scalar measurements and attempts to reconstruct the original velocity field from them. It is possible to experimentally determine time-dependent, turbulent flowfields from measurements of a passive scalar that is convect...

Description
Summary:A study uses the subsets of the scalar grid function that were generated as the scalar measurements and attempts to reconstruct the original velocity field from them. It is possible to experimentally determine time-dependent, turbulent flowfields from measurements of a passive scalar that is convected by the flow if measurements of scalar data are sufficiently accurate and well resolved.
