We have developed a method of estimating the zeta potential distribution along the microchannel wall using velocity measurements of the EOF. The relevant inverse problem is solved through the minimization of a performance function utilizing the conjugate gradient method. Employing a set of simulated velocity measurements, which is constructed by adding random noise to the computed exact velocity, the present method is found to estimate the distribution of the zeta potential along the channel wall with reasonable accuracy.
我们开发了一种利用电渗流(EOF)速度测量来估计微通道壁面zeta电位分布的方法。通过使用共轭梯度法最小化性能函数来解决相关的反问题。利用一组模拟速度测量值(通过向计算出的精确速度添加随机噪声构建而成),发现本方法能够以合理的精度估计沿通道壁面的zeta电位分布。
