✦ Synopsis

We present a review of the development of techniques available for the measurement of granular temperature in three dimensional dry granular flows, principally discussing positron emission particle tracking and magnetic resonance imaging. We will show how these techniques have given unique insight into granular behaviour, demonstrating phenomena such as buoyancy driven flows, non-equipartition and segregation, whilst also providing us with vital benchmark data for validating kinetic theory based models of rapid granular flow.

The characteristics of continuous, steady granular flow through a flat-plate orifice have been experimentally investigated. In particular, the normal stress exerted on the orifice plate has been measured by the normal stress gauge which consists of a strain gauge attached to a cantilever beam. The c

Discrete element based simulations of granular flow in a 2d velocity space are compared with a particle code that solves kinetic granular flow equations in two and three dimensions. The binary collisions of the latter are governed by the same forces as those governing the discrete elements. Both met
