The Flow Losses at 90 Degrees Turns in Pneumatic Dust Transport

Abstract

Measurements of the pressure course in dust-laden air flows prior to and following curves of various configurations indicate the pressure drop caused in a permanent manner by the curve. This pressure drop is caused by the energy consumption during the reacceleration that follows the turn and is required to compensate for the friction that develops. The measured values characterize the transition between the ultimately developed states of the transport process before the turn and upstream.
