Abstract

This paper presents a detailed investigation into the modeling of the total bend pressure drop (TBPD) for all three orientations: horizontal-horizontal (H-H), horizontal-vertical (H-V), and vertical-horizontal (V-H) in dilute phase flow. Different types of materials were fed with a screw feeder and conveyed through two different sets of galvanized steel pipeline. The TBPD (all orientations) is the summation of the pressure drop due to the momentum change (reacceleration), the air only flow along the bend, and a function of the pressure drop due to the particles, which contributes to the bend only. A qualitative comparison was performed for blind-T and a radius bend (R/D = 10) using a particular material property. This comparison helped in obtaining a comprehensive understanding of TBPD.
