Studies of small particle suspensions for L.M.F.R. Part VI concentration profiles across a bend and vertical pipe

Abstract

This report completes the work on suspension studies for L.M.F.R. Concentration profiles have been measured for a tungsten suspension flowing through a smooth elbow and a vertical pipe. It has been shown that uniform suspension at a smooth elbow is not achieved for velocities up to 13.8 feet per second. Approximately four feet of vertical pipe is required after the smooth elbow to destroy the gradients set up in a horizontal pipe for velocities of approximately 3 and 13.5 per second. No evidence for "coring" was found.
