A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles. The resulting medium then has many properties and characteristics of normal fluids, such as the ability to free-flow … WebSep 29, 2024 · Pumping requires a fluid that you can compress in the pump so there is a pressure difference that transfers force to other particles. Although it's easy to lift particles to the top of a pipe and have them flow down, it's less clear how you can pump solid sand particles up without using some carrier fluid like air or water.

WebNov 29, 2024 · As Rober explains in the video, the "liquefied soup" is actually what scientists call a "fluidized bed." Basically, when you blow air into the bottom of a container of sand, you increase the space between individual sand particles. This reduces internal friction and allows the particles to move around more freely, the way they do in a liquid.
