Other AbstractAn experimental apparatus was established to study the heat transfer and flow resistance characteristic of trefoil expansion tube. Based on the experimental results, the reliability of the computational model was verified, and the performance of trefoil tubes with different structure parameters was investigated by FLUENT software. The simulation results show due to the special spiral shape, the flow pattern is presented as three dimensional longitudinal helical flow. The secondary flow which is perpendicular to the main stream is formed in the tube, and it is mainly distributed in the three expansion areas. The generation of secondary flow promotes the fluid radical mixture, and increases the disturbance of boundary layer, thus enhances the heat transfer. The heat transfer and resistance factor increase with twisted pitch and inscribed circle diameter decreasing, reduce first and then increase with transitional arc diameter decreasing.
