摘要: <正>壳程轴流式换热器是70年代发展起来的一种新型换热器,其显著特点是流体阻力低,传热效率好,在大流量的场合较适用.实验结果表明,该类换热器阻力系数与管子的种类及排列方式等因素相关[门,如何恰当地关联与这些因素之间的关系

Abstract: The calculating formula of flow resistance of heat exchanger with longitudinal fluid flow on shell side is derived by the method of regarding zero shear stress line as separate boundary of tube unit. The parameters are derived by experiment , and the variations of flow resistance correspond with experiment data . The maximum deviation with experimental data is less than 6% .
