Get Price2018-2-23 · This study investigates the effect of nozzle geometry on the intermingling process. The dimensions of intermingling nozzles with single air inlets extended across the width of a rectangular yam channel are systematically varied. Nozzles with this cross-sectional shape prove to be easy to manufacture and efficient at intermingling.
