Due to the contact and tribo-friction between the solid-liquid phases, the non-aqueous working fluids in these systems acquire net free charge; the free charge is then convected downstream, and is either relaxed or grounded through the system pipelines, or accumulated within the flow loop resulting in a rise or increase in the electrical potential of the system. If there are no proper mechanisms designed for these systems to relax, conduct, and ground the accumulating free charge, the excessive accumulated free charge as well as electrical energy will eventually cause destructive failure of these engineering systems. Based on the fundamental principles of fluid mechanics, heat and mass transfer, and electromagnetism, this research project is therefore aimed at investigating how to recycle the potentially hazardous and destructive energy originating from flow electrification of non-aqueous fluids in the above described engineering systems such that we can not only provide a new strategy and solution to the issue of sustainable energy, but also resolve the minor/major pollution and safety hazards as well as threats posed by flow electrification in different fields of engineering.流動帶電靜電危害流動電位能源回收永續能源flow electrificationelectrostatic hazardstreaming potentialenergy recyclingsustainable energy
