Implication

Experimental and numerical investigation reports xanthan gum's drag reduction and heat-transfer characteristics in turbulent flow, indicating a hydraulic-thermal trade-off.

Key Points

This research aims to explore the impact of xanthan gum solutions on drag reduction and heat-transfer characteristics in turbulent pipe flow under varying temperatures and concentrations.
Combined experimental and numerical investigation of xanthan gum solutions at 100 and 300 ppm.
Pressure-drop data were analyzed to evaluate drag reduction behavior.
Numerical simulations assessed flow and heat-transfer responses under Reynolds numbers of 8000–12,000.
XG 100 ppm achieved a drag reduction of approximately 31–39%, while XG 300 ppm ranged from 25–45%.
Water displayed higher Nusselt numbers (approximately 68–106) than XG solutions, with XG 100 ppm at 45–69 and XG 300 ppm at 35–61.
Heat-transfer reductions were 26–48% for XG 100 ppm and 23–46% for XG 300 ppm.
