| Zusammenfassung | Flow electrification constitutes a significant hazard to operational safety in industry and for this reason it has been studied in detail over the years. It is generally accepted that the impact of turbulence on the electrification of liquids is of paramount importance. More specifically, at sufficiently high Reynolds numbers and for low-conductivity liquids such as hydrocarbons, the thickness of the hydrodynamic boundary layer can become comparable to that of the electrical double layer. This can lead to increased charge diffusion towards the bulk of the flow and, subsequently, flow electrification. However, quantitative information of the underpinning mechanisms of this phenomenon is still lacking. In this paper we present a computational framework for the study of electrification of turbulent liquid flows via numerical simulations. First, we provide a brief description of the physical problem in hand and elaborate on the interaction between the fluid and the electric field. Subsequently, we present the governing equations and the accompanying boundary conditions. Next, we describe the proposed algorithm and elaborate on its implementation in pafiX, which is a computational tool for the simulation of fluid flows related to explosion protection. Finally, we present results from numerical tests that we performed in order to access the efficacy of the proposed computational framework. |
