The authors present a survey of air/water and air/water/sand flow through circular and triangular pipes. The main objective of this investigation is to study the potential effects of triangular pipe geometry on flow patterns, slug frequency, sand erosion in elbows, and heat transfer in multiphase flow.
Introduction
The complete paper summarizes several important benefits of triangular pipes as compared with circular pipes in multiphase flow. First, a survey of horizontal multiphase air/water flow through circular and triangular pipes is presented. Second, the erosion patterns in triangular elbow geometry are examined experimentally and predicted computationally using existing erosion models.
