“Solids Handling – from Fundamental Theory to Practical Applications”

Abstract

This course offers a practical approach to tackle solids handling problems, from properly designing the equipment to systematically analyze operational problems for troubleshooting. It covers both bulk powders and solids in fluid. The course begins with an overview of the fundamental theories behind the physical phenomena such as forces among solids, flow of solids, surface properties, and so on, followed by the development of engineering models that are useful in finding a practical solution. A number of typical problems in solids handling will be presented to illustrate the approach.

Who should attend?

The course is directed at chemists and engineers engaged in the development of processes or operations that involve handling and processing of solids.
