Advanced Powder Flow Course: focus on electrostatics

It is well known that electrostatic charges induce problems during powder processing. Triboelectric charges are produced during powder flow at the contacts between the grains and at the contacts between the grains and the container. The presence of these electrostatic charges induces adhesion and cohesiveness leading to intermittent or blocked flow. More serious consequences are possible such as dust explosions. Powder electrostatics is also a concern in major challenges like space exploration.

Unfortunately, the fundamentals behind the triboelectric effect are still poorly understood in the framework of industrial applications and the empirical approach is still the norm.

In this advanced course focused on powder electrostatics, we will review the recent advances in physics from a fundamental point of view before focusing on applications. Moreover, we will show how to perform reproducible electrostatic measurements on powders. Finally, we will see how to take advantage of electrostatic charges in some application or to avoid electrostatic charge build-up in other applications.
