👉 The p-fluid, also known as plasma-fluid interaction (PFI) fluid, represents the complex interplay between plasma and the surrounding medium in fusion devices like tokamaks. It is a highly ionized gas consisting primarily of ions and free electrons, where the plasma's behavior is significantly influenced by electromagnetic fields generated by the fusion process. This interaction leads to unique phenomena such as pressure gradients, magnetic confinement effects, and energy transfer between the plasma and the walls of the device. Understanding p-fluid dynamics is crucial for optimizing fusion reactor performance and achieving stable, sustained nuclear fusion reactions.
