【Abstract】 The heat transfer and flow resistance of the single phase oil in the common spiral fluted tubes and the newly developed W-shaped spiral fluted tubes were studied,they were compared with the circular smooth tubes,and the corresponding expressions of the heat transfer and flow resistance were concluded. The research result provided a theoretical basis for the design and improvement of the heat exchangers with oil as medium.更多还原
