• Large Scale Systems – Marcus et al. (1986) and Wypych (1999) both took the realm of pneumatic conveying research from what some industrial practitioners call tools to reality by implementing large scale testing with industrial size pipeline both in diameter and length. Industry had to listen to these researchers and could not just pass off University work as cute
and that is a nice toy. These studies have been transformative in providing more respect for University scale research because they did show that the smaller scales could provide interesting and useful information for industry. Understanding the scaling parameters can be credited to their transformative work.
