Al-Tameemi, W.T. and Ricco, P. (2018) Pattern-based Pressure Drop Of Air–water Flow Across A 90° Sharp Mitre Elbow. International Journal of Computational Methods and Experimental Measurements, 6 (1). pp. 198-207. ISSN 2046-0546
Abstract
Air–water flow in a 90° sharp elbow (mitre bend) is studied in a new purpose-built experimental facility at the University of Sheffield. For the first time, the two-phase flow is investigated in a mitre bend for water-based Reynolds numbers Rew = 5600–12800 and water-to-air mass flow rate ratios mw/ma=10–3800. Four different flow patterns are observed in the upstream pipe (plug, slug, slug-annular and annular) by using a high-speed high-resolution camera. The results show that the perturbation length upstream and downstream of the elbow and the pressure drop are significantly affected by the flow patterns. Two new values of the Lockhart–Martinelli parameter C are found for the pressure drop across the elbow.
