Abstract
We derive the formalism to obtain spatial distributions of collisional corr elation times for macroscopic particles undergoing granular flow from pulse d gradient spin echo nuclear magnetic resonance diffusion data. This is dem onstrated with an example of axial motion in the sheer flow regime of a 3D granular flow in a horizontal rotating cylinder at one rotation rate.
