Hydrodynamic dispersion in shallow microchannels with almost parabolic cross-sectional shapes and with heights much less than their widths is studied experimentally. Both long serpentine channels and rotary mixers are used. The experimental results demonstrate that the dispersion depends on the width rather than the height of the channel. The results are in quantitative agreement with a recently proposed theory of dispersion in shallow channels.
对横截面形状近乎抛物线且高度远小于宽度的浅微通道中的流体动力学弥散进行了实验研究。使用了长蛇形通道和旋转混合器。实验结果表明，弥散取决于通道的宽度而非高度。这些结果与最近提出的浅通道弥散理论在定量上是一致的。
