Wall Flows and their Applications

Abstract

So-called wall flows are usable in many technical applications as a simple and reliable device for exhausting of light materials as dust, smoke, hot air, etc. In another cases, such flows can make troubles by treatment of light materials as fibers, etc. and it is necessary to suppress the wall effects by suitable design adjustments. But there is described a useful effect of wall flows on quality of fibrous product, too.

Vortex Valve – Principle, Design and Application

“…Some improvement of it gives the chamfered outer edge, where the flow adheres to the chamfering and dissipates in the radial direction. The effect is known from so-called wall nozzles -for suitably designed dimensions the outflow can be bent of over 180° [14,15] etc.…”
