摘　　要：“边界层”概念贯穿于动量传递、热量传递、质量传递之中。通过流体边界层归纳出“边界层模型”在处理传递过程中的内部共性关联,继而推导出归一化的传递通量的基本模型,并推导出求解动量、热量、质量传递通量的关键参数分别为摩擦系数λ、对流传热系数ɑ、传质系数k。同时,通过理论推导揭示了传递过程的共性规律,预期使学生加深对化工传递过程的理解,并提高他们解决实际工程问题的能力。The concept of“boundary layer”is prevalent in the momentum transfer,heat transfer and mass transfer.The correlation of“boundary layer”for transfer processes was summarized by boundary-layer flow,and then the model of normalized transfer flux.Accordingly,the key parameters for solving the momentum,heat transfer and mass transfer flux were obtained as friction coefficient,convective heat transfer coefficient and convective mass transfer coefficient,respectively.Reveals the common laws of the transfer processes through theoretical deduction,in order to help students deepen the understanding of transfer processes and improve the ability for practical engineering problems.
