Form 15 (3/31/86) NSF PROJECT IST-850 5411 EXPERIMENTS ON THE COGNITIVE ASPECTS OF INFORMATION SEEKING AND INFORMATION RETRIEVING USER QUESTIONS FOR ONLINE SEARCHES QUESTION NUMBER: 033 A1. BRIEF TITLE: Slurry-flow friction factors derived from volume-averaged equations A2. QUESTION STATEMENT: The form of friction-factor (drag coefficient) correlations for 2-phase slurry flow in pipelines is based on analogy with pipeline flow of single-phase fluids. Recently (last 15 years) volume-averaged governing equations have been developed for general multiphase systems. It is our intention to use these volume- averaged equations as a basis for determining the functional form that slurry- flow correlations should have. The question that we need to know the answer to is "Has this been done before?" Key words: Volume-averaging Multiphase Theory Two-phase flow Slurry and bubbly flows Friction factors Drag coefficients Dimensional analysis Settling Pneumatic conveying TYPE OF SEARCH REQUESTED B.
