摘要

尽管热量和质量的传递过程涉及高压下降,微通道仍被用于涉及极高效热量和质量传递过程的研究中,例如肺部和肾脏系统。由于微通道具有较高的表面体积比和紧凑的体积,因此具有卓越的热性能。微通道流已被证明是一种高性能的冷却方法,它能将局部微小热点的热流分散到较大的表面积上。由于细胞粘附处的信号具有双向性,因此有必要研究与生理相关的微环境中的机械传导。由于需要在具有生理相关机械特性和结构的环境中研究机械传导,因此开发了微流控平台来改进标准体外细胞培养。本文通过强调微通道中的热流耦合效应,强调了工作流体内部温度和速度变化的调制。在两种输入边界条件的情况下,数值研究了热分布对微通道内微鳍流体流动的影响。比较两种边界条件的结果后发现,矩形鳍片对流体流动的传热量最高,而半椭圆形鳍片的传热量最低。

Influence of the presence of different signatures on the heat transfer profile of laminar flow inside a microchannel.
Despite the fact that the process of transferring heat and mass involves a high-pressure decline, microchannels are utilized in research involving extremely efficient heat and mass transfer processes, such as in the systems of the lungs and kidneys. Due to their high surface-to-volume ratio and compact volume, microchannels have demonstrated superior thermal performance. Microchannel flows have been shown to be a high-performance cooling method that dissipates heat flux from tiny localized hot spots over a large surface area. Due to the bidirectional nature of signalling at cell adhesions, it is necessary to examine mechanotransduction in microenvironments that are physiologically pertinent. The need to enable the study of mechanotransduction in environments with physiologically relevant mechanical properties and architecture had prompted the development of microfluidic platforms that improve standard in vitro cell culture. This article emphasizes the modulation of temperature and velocity variations within the working fluid by emphasizing the thermo-fluid coupling effects in micro-channels. In the case of two input boundary conditions, the effect of heat distributions on fluid flow with respect to micro-fins within a microchannel was investigated numerically. After comparing the results for both boundary conditions, it was found that rectangular fins had the highest heat transfer to the fluid flow, while semi-elliptical fins had the lowest heat transf
