摘要

摘要: 研究了偶应力流体在微通道中的非Fourier热传导特性, 分析了偶应力参数、Hartmann数、Joule热效应和双相滞后时间参数对流体温度分布和热传递特性的影响.通过建立相关的控制方程, 结合非Fourier热传导模型, 研究了不同物理效应的作用.结果表明, 偶应力流体的流动性和热扩散特性受到上述参数的显著影响.偶应力参数的增大加剧了温度梯度的变化, Hartmann数则增强了磁场对流体的约束, 抑制了热传导; Joule热效应促进了温度梯度的增大, 突出了非Fourier效应; 双相滞后时间参数的变化对温度峰值及响应速度具有明显调控作用.

Abstract: The non-Fourier heat transfer characteristics of couple stress fluid in a microchannel were investigated, and effects of the couple stress parameters, the Hartmann number, the Joule heating effect and the 2-phase lag time parameters on the temperature distributions and heat transfer characteristics of the fluid were analyzed through establishment of the relevant governing equations combined with the non-Fourier heat transfer model. The results show that, the above parameters significantly influence the fluidity and heat diffusion characteristics of the couple stress fluid. The increase of the couple stress parameter aggravates the temperature gradient; the Hartmann number enhances the magnetic field confinement and inhibits the heat conduction; the Joule heating effect promotes the temperature gradient and highlights the non-Fourier effect; and the change of the biphasic hysteresis time parameter has a significant modulation effect on the temperature peak and the response speed.
