Abstract:: Flow and heat transfer charaeteristies of convex eorrugated tube, coneave corrugated tube and bel.lows corrugated tube are studied, based on the k-s model with numerieal comparative method, the flow andheat transfer performanee with the changes of Re is obtained; The heat transfer mechanism and the resistaneemechanism are analyzed, the main eauses of loss in heat transfer and pressure drop are detected. The perform.anee of the corrugated tube is analyzed in heat transport potential capacity( Entransy), and the entransy differenee , AE, belween inlet and outlet with the changes of Re is acguired.
