What type of current charge is referred to as a 'streaming current charge'?

The term 'streaming current charge' pertains specifically to the flow of charge in a moving fluid. This phenomenon occurs when charge carriers, such as ions or electrons, are transported in a fluid dynamic, leading to the generation of electrical currents as the fluid moves. In many contexts, especially regarding electrochemistry and fluid dynamics, the movement of charged particles within a fluid can result in varying electrical properties of that fluid and may even influence processes such as corrosion or foaming in industrial applications.

While static discharge from a spark, charge build-up during brush discharge, and constant electrical charges in stationary conditions involve the movement or accumulation of electrical charge, they do not encompass the concept of flow in conjunction with fluid movement. Streaming current specifically highlights the active transport of charge within a dynamic medium, setting it apart from these other scenarios.
