摘要
///According to the electrical double-layer model and the electrochemical theory,the authors derived the coupling relationships between flow field,ion field and current field based on the capillary model.The influences of pore structure parameters on the coupling coefficient of streaming potential were obtained by numerical simulation.The results show that the absolute value of coupling coefficient of streaming potential increases with the increasing solution concentration,cation exchange capacity,porosity and permeability.
