提出了管内核心流强化传热的方法,其原理是通过在充分发展的管内层流核心流区域采取强化传热措施,从而在管内壁附近形成一个等效的热边界层,以加大壁面附近流体的温度梯度,达到强化表面换热的目的,但又不显著地增加流动阻力.对空气和水2种流体的分析比较和计算结果说明:管内核心流传热强化的原理和方法对指导高效-低阻热交换器的设计具有一定的意义. A method to enhance the heat transfer in the core of the pipe is proposed. The principle is that an effective thermal boundary layer is formed near the inner wall of the pipe by adopting the enhanced heat transfer measures in the well-developed inner core flow area, so as to increase the area near the wall Fluid temperature gradient to achieve the purpose of strengthening the surface heat transfer, but not significantly increase the flow resistance.Analysis of air and water two fluid comparison and calculation results show that: the principle and method of heat transfer in the core of the tube to guide efficient - Low resistance heat exchanger design has some significance.
