Experimental Investigation of Heat Transfer Rates in Water Coils Under Various Flow Conditions

Abstract

This study investigates the influence of various flow conditions on heat transfer rates in water coils through experimental analysis. Water coils, crucial for efficient thermal management in industrial applications, were tested under different flow rates and orientations to assess their impact on heat transfer performance. The experiment involved measuring heat transfer coefficients and pressure drops for coils subjected to flow rates ranging from 0.5 to 5 L/min and comparing results across laminar and turbulent flow regimes. The findings reveal that increasing flow rates generally enhance heat transfer rates, though the improvement diminishes at higher flow rates due to flow-induced turbulence. Additionally, coils with helical arrangements demonstrated superior heat transfer performance compared with straight coils. The study underscores the importance of balancing flow rates and pressure drops to optimize coil performance, providing valuable insights for the design and application of heat exchangers.
