Numerical investigation of electric charge measurement by PWP method at solid and liquid interfaces
Year: 2024
Type: article
Abstract: When a liquid contacts a solid, physicochemical reactions form an electrical double layer (EDL) at the interface. Understanding the EDL is crucial to prevent electrical device failures, but few experimental methods can access this charge distribution. Recently, the pressure wave propagation (PWP) method has been explored. This paper presents simulations of current generated by a pressure wave through the EDL using the finite difference time domain (FDTD) method. A parametric study investigates the effects of EDL parameters and stimulus properties on the signal. Simulations with EDL data obtained experimentally for both conductive and dielectric liquids are carried out.
