摘要

摘要: 弯曲微通道在电渗流及其传热方面展现出显著的优势,包括增大电渗流速度和提高传热效率.同时,纳米流体因其优良的传热性能也受到广泛关注.然而,目前关于弯曲微通道内纳米流体的电渗流及传热机理的研究仍显不足.该研究旨在探讨在低 zeta 势和恒壁面热流密度条件下,弯曲微通道的几何效应对微通道中纳米流体的电渗透流动及换热特性的影响.研究中考虑了蠕变Dean流,由于不存在向心力,速度场保持直线分布.利用Fourier变换方法得到了速度和温度的半解析解,进而推导出了Nusselt数Nu的数学表达式.通过分析速度、温度和Nu随曲率比δ、纳米粒子体积分数φ、特征压力速度和特征电渗速度之比u_r等相关物理参数的变化趋势,揭示了这种流动和传热现象的特性.结果表明,Nu随着压力速度的增大而减小,随曲率比的增大而减小,而随着纳米粒子体积分数的增大而增大.该文的结果为微纳米流体器件的设计和应用提供了重要的参考价值,有助于优化器件性能和应用.

Abstract: Curved microchannels exhibit significant advantages in electroosmotic flow and heat transfer, including increased electroosmotic flow velocities and improved heat transfer efficiencies. At the same time, nanofluids have received widespread attention due to their excellent heat transfer performances. However, current research on the electroosmotic flow and heat transfer mechanisms of nanofluids within curved microchannels remains insufficient. Herein, the effects of the geometry of curved microchannels on the electroosmotic flow and heat transfer characteristics of nanofluids in the microchannels were investigated at low zeta potentials and constant wall heat fluxes. The creeping Dean flow was considered, and the velocity field was kept in a straight line distribution due to no centripetal force. The semi-analytic solutions of velocity and temperature were obtained with the Fourier transform method, and the mathematical expression of Nusselt number Nu was derived based on the velocity and temperature solutions. The variation trends of the velocity, the temperature, and Nusselt number Nu with curvature ratio δ, nanoparticle volume fraction φ, and the ratio of the characteristic pressure velocity to the characteristic electroosmotic velocity u_r, were analyzed, with the characteristics of the flow and heat transfer phenomena revealed. The results show that, Nusselt number Nu decreases with the pressure velocity and the curvature ratio, and increases with the nanoparticle volume fraction. The work provides an important reference for the design and application of micro and nano fluid devices, and helps to optimize the device performances and applications.
