We have studied the effect of flap parameters on fluid rectification in a microfluidic diode. We use Navier-Stokes equations and arbitrary Lagrangian-Eulerian formulation to obtain dynamics of fluid flow and motion of the flap. The flap opens during forward flow and seals against a stopper during reverse flow. This allows flow in the forward direction and prevents it in the reverse direction. The rectifier is fluidic analog to a semiconductor diode in function because it rectifies fluid flow. Velocity-pressure (V-P) curves analog to the current-voltage (I-V) curves of the electronic diode has been obtained. The effect of the flap parameters, such as length, thickness, and Young's modulus has been found out. The transient response of the flap and fluid flow under oscillating pressure driven flow has also been obtained.
我们研究了微流道二通阀中阀瓣参数对流体整流的影响。我们使用纳维-斯托克斯方程和任意拉格朗日-欧拉公式来获得流体流动和阀瓣运动的动力学。阀瓣在正向流动时打开，在反向流动时关闭以密封止动器。这允许正向流动并防止反向流动。该整流器在功能上是流体对半导体二极管的模拟，因为它整流了流体流动。已经获得了类似于电子二极管的电流-电压（I-V）曲线的速度-压力（V-P）曲线。已经发现了阀瓣参数（如长度、厚度和杨氏模量）的影响。还获得了在振荡压力驱动流下阀瓣和流体流动的瞬态响应。
