摘要:
通过数值模拟计算,探讨脉冲流对波节管对流换热的强化机理.研究表明:脉冲流强化效果与速度和频率有关,与稳流相比脉冲流可使波节管换热效果提高90%.脉冲流强化换热原因是脉冲流使得波节管波节处产生漩涡,增强扰动,减少热边界层厚度.
Abstract:
Heat transfer enhancement of corrugated tube is investigated through numerical simulation.The effect of heat transfer enhancement depends on the Reynolds number and the vibration frequency.The numerical results indicates that compared with the steady flow, the pulsating flow increases the heat transfer efficiency of the corrugated tube flow by 90% most. Heat transfer enhancement of pulsating flow is due to the pulsating flow which makes corrugated tube generate whirlpools and increase disturbance and reduce the thermal boundary layer thickness.
