| Abstract: | In response to fundamental theory of fluid mechanics and heat transfer,general model for the theoretical calculation of the tube-side was developed for the longitudinal flow shellandtube excanger with mixed bundle of the Varing-area tubes and plain tubes and without the need for baffles (RODbaffle). By means of the measured data of experiment and utilizing the leastsquare method,connected equations of heat transfer coefficient and resistance coefficient were arrived. At last calculation equations of the deformed tube heat rtansfer and pressure drop in the tube-side were acquired. |
