Drag Reduction Effects of Micro-Bubbles in Straight and Helical Pipes

Drag Reduction Effects of Micro-Bubbles in Straight and Helical Pipes

Experimental investigations were conducted to study the effect of micro-bubbles injected into water flowing through straight and helical pipes with different curvature ( 0.025, 0.05 and 0.1). The micro-bubbles were produced using two hydrocyclone micro-bubble generators positioned face to face with...
