Frictional Pressure Drop of Air Non‐Newtonian Liquid Flow through Helical Coils in Horizontal Orientation

Abstract: On a effectué des recherches afi n d'évaluer la perte de charge frictionnelle diphasique pour un écoulement liquide non newtonien d'air dans des serpentins hélicoïdaux orientés horizontalement. Les expériences ont été menées avec trente-six serpentins hélicoïdaux différents et quatre concentrations différentes de sel de sodium de carboxyméthylcellulose (SCMC) comme liquides non newtonien. Les effets du débit d'air et de liquide, du diamètre de serpentin, de l'angle d'hélice et des propriétés de liquide sur la … Show more

“…Guan and Martonen simulated by using CFD to observe the developing length of velocity patterns and transitional character of fluid flowing in curved geometry [10]. Earlier, frictional pressure drops of air non-Newtonian liquid flow were analyzed through helical coils in horizontal orientation [11]. The pressure drop in helical coil was predicted with single phase flow of non-Newtonian fluid [12].…”
