建立了一个深度平均的数值模型来理解实验观察到的基于绝缘体的介电微器件中诱导电荷电渗和电热流的相互作用。实验测得的非线性流体速度与低浓度缓冲器中电渗流和高浓度缓冲器中电热流的预测速度基本匹配。这一协议与比例分析一致。
A depth-averaged numerical model is developed to understand the experimentally observed interplay of induced charge electroosmosis and electrothermal flow in an insulator-based dielectrophoresis microdevice. The experimentally measured nonlinear fluid velocity matches asymptotically the predicted velocity of the electroosmotic flow in a low-concentration buffer and that of electrothermal flow in a high-concentration buffer. This agreement is consistent with a scaling analysis.
