Abstract

This paper has dealt with the heat transfer enhancement of flowing water with flow drag reduction additive into a heat transfer tube by inserting wire coils. The non-ion type surfactant was used as the additive to decrease the pipe flow resistance for the heat energy transport system. However, the decrease in the flow resistance was allowed to reduce the heat transfer coefficient in the heat transfer tube. Some kinds of wire coils having different diameters were tried to enhance the heat transfer in the heat transfer tube. The effects of wire coils on the pipe friction and the heat transfer coefficients were elucidated under various experimental parameters of flow velocity, wire coil diameter, pitch and length.
