| 摘 要： | 建立了纳米流体脉动热管的分析模型,将相变传热项合理引入了汽塞能量微分方程;液塞动量方程中考虑了剪切力的影响;纳米流体的物性采用了当量处理方法.采用数值迭代方法进行了求解,得到了汽塞压力、温度、质量的变化波形,分析了波形的频率,进而解释了初始条件、重力等对脉动热管的流动与传热影响的机理.

| Abstract: | A nano-fluid pulsating heat pipe is modeled with a term of phase-change heat transfer properly added into the vapor differential energy equation.The shear stress is considered in the moment equation of liquid slug.The physical properties of nano-fluid are given by the effective quantity method.The results of pressure,temperature and mass for vapor plugs are obtained by the numerical iterative.The circular frequency of oscillation is discussed.Furthermore,the mechanism influence of initial conditions and gra... |
