摘要：

An experimental investigation was carried out to determine the pressure drop and heat transfer characteristics for spirally fluted tubes in laminar, transitional and turbulent flow of air. In the laminar, transitional and turbulent regimes, the friction factor for the spirally fluted tube is generally higher than that for a smooth tube. The experimentally determined Nusselt numbers are generally higher than the smooth tube values.
