Granular Flows Through Nonaxisymmetric Hoppers

Abstract

Granular materials are a vital component of many industries, including
the pharmaceutical, mining, and food industries. Often hoppers of
various sizes and shapes are used in the handling of these materials.
Despite the importance of these structures, most modeling is done in
simple axisymmetric geometries in which the flow assumes a very simple
form that is ill-suited for more general geometries. We construct a
problem for similarity solutions in more general nonaxisymmetric hoppers
and through computation show that the flow becomes fully
three-dimensional. Furthermore, we examine the effect of the geometry on
the distribution of stress along the hopper walls and indicate the
importance that this work may have for design of better structures.

2. For students

Thursday, February 19, EMCS 211, 9:25am.

An Introduction to Granular Materials

Abstract

Granular materials are a vital component of many industries, including
the pharmaceutical, mining, and food industries. Equally important,
however, are the mathematical and computational questions raised in the
course of modeling these materials. This talk will serve as a gentle
introduction to the field, covering a range of applications from
Engineering and Physics and explaining how Mathematics has been brought
to bear on these problems.
