大多数微型设备通常是根据工程师的经验临时开发的--没有开发微型设备的系统程序。本研究以板翅式微器件的设计问题为研究对象，利用计算流体力学(CFD)技术研究了板翅式微器件内部的流动特性，作为微器件系统设计的第一步。模拟结果表明，支管形状、翅片长度和位置以及进口流量对分支微通道间的流动均匀度有很大影响。提出了一种基于CFD的板翅式微器件优化设计方法。利用该方法，可以自动求出在流动均匀度约束下使时空最小的最优流形。该方法有可能成为各种器件的优化设计工具。(C)2004爱思唯尔B.V.保留所有权利。
Most microdevices are usually developed ad hoc, on the basis of engineers' experience-there is no systematic procedure for developing a microdevice. In this research, as the first step for the systematic design of microdevices, a design problem of a plate-fin microdevice was focused on, and characteristics of flow pattern inside plate-fin microdevices were investigated by using computational fluid dynamics (CFD). The simulation results show that the flow uniformity among branched microchannels depends largely on shapes of manifolds, length and location of fins, and inlet flow rate. A CFD-based optimization method is proposed for the design of plate-fin microdevices. With the proposed method, the optimal manifold shape that minimizes space time under the constraint on flow uniformity is automatically derived. The proposed method has a potential as an optimal design tool for various devices. (C) 2004 Elsevier B.V. All rights reserved.
