5), the current density in the edge of the metal disk exists in standing wave form, meanwhile, there is a great phase difference of current density between edge of disk metal and the helical line.
The helical coil element is primarily an impingement separation device much like vane or mesh pad types, but utilizes inertial forces in such a manner that greatly improves separation efficiencies over a wide flow range without any change in particle removal efficiencies.
Tesco has already gained planning permission for its scheme, while Helical is in the process of doing so.
In cross-grain helical planing, superficial cells are often pulled out and raised, leaving small longitudinal grooves and also a fuzzy texture (de Moura and Hernandez 2006a), In contrast, surfaces obtained by fixed-oblique knife pressure-bar cutting present plateau-like regions, with virtually no sign of fibrillation, which reduces roughness (de Moura and Hernandez 2006c).
