👉 The term "knudsen" is a technical term in the field of fluid dynamics and heat transfer. It refers to a specific type of flow that occurs when a fluid flows with a velocity that exceeds the speed of sound in the fluid, as measured by the Knudsen number (Kn). The Knudsen number plays a crucial role in the design of various processes, including heat exchangers, turbines, and pumps.
