磁流体力学（MHD）在基于微流体的应用开发人员中日益流行，例如“芯片实验室”（LOC）和/或“微型全分析系统”（micro-TAS）。它的物理特性使流体操纵的任务，如泵送，网络，推进，搅拌，混合，甚至冷却，而不需要机械部件，其非侵入性的性质提供了一个解决方案，机械系统的问题。然而，这些都不是容易的任务。它们都需要精确的流量控制，这取决于几个参数，如微流体电导率，微流体导管（通道）形状和尺寸配置，以及磁场和电场之间的相互作用。这导致需要在理论和实验上验证的数学模型。本文介绍了在洛仑兹力作用下，环形开口流道内含电解质的三维层流流动的设计。首先介绍了MHD在微流控领域的应用，然后对所提出的MHD微流控系统进行了总体描述，然后重点对数学模型进行了理论验证，接着描述了利用定制的视觉系统对数学模型进行的实验验证，最后对结论和未来的工作进行了展望。
Magnetohydrodynamics (MHD) is becoming more popular every day among developers of applications based on microfluidics, such as “lab on a chip” (LOC) and/or “micro-total analysis systems” (micro-TAS). Its physical properties enable fluid manipulation for tasks such as pumping, networking, propelling, stirring, mixing, and even cooling without the need for mechanical components, and its non-intrusive nature provides a solution to mechanical systems issues. However, these are not easy tasks. They all require precise flow control, which depends on several parameters, like microfluidics conductivity, the microfluidics conduit (channel) shape and size configuration, and the interaction between magnetic and electric fields. This results in a mathematical model that needs to be validated theoretically and experimentally. The present paper introduces the design of a 3D laminar flow involving an electrolyte in an annular open channel driven by a Lorentz force. For an organized description, first of all is provided an introduction to MHD applied in microfluidics, then an overall description of the proposed MHD microfluidic system is given, after that is focused in the theoretical validation of the mathematical model, next is described the experimental validation of the mathematical model using a customized vision system, and finally conclusions and future work are stated.
