Abstract: The experimental friction factor and Nusselt number data for a laminar flow in a circular pipe having wire coil and wavy strip insertion are presented. Thermal boundary layer is the primary hindrance to the heat transfer. That is why to destroy it or at least to disturb it the insertions are used. The thermohydraulic phenomenon has been analyzed. The objective of this work is to find out the combined effect of wire coil and wavy strip on the heat transfer and whether it can enhance it. Nusselt number and friction factor are measured for different Prandtl number and Reynolds number. The findings of this work are useful in automobile and air-conditioning industries to reduce the size of the heat exchanger.
