WebApr 12, 2024 · 3.1 Thermo-Physical Property Database of Blanket Material. The thermo-physical properties for coolant and material are important elements of the fusion reactor database, and the various materials in the normal operating conditions of the blanket and in accident conditions need to be in a safe state, so before analyzing the safety of the … The solid substrate material (the catalytic material upon which chemical species react) in the fluidized bed reactor is typically supported by a porous plate, known as a distributor. The fluid is then forced through the distributor up through the solid material. At lower fluid velocities, the solids remain in place as the fluid passes through the voids in the material. This is known as a packed bed reactor. As the fluid velocity is increased, the reactor will reach a stage where the force of t…
