Packed Bed Project Description
In this project, which has been done by the CFD simulation method with the help of Ansys Fluent software, the gas flow passing through the packed bed is simulated. The gas used is argon monoatomic gas, which enters at a speed of 4 m/s and for the outlet is defined zero Pascal gauge pressure. The packed bed area is a porous medium with an inertial resistance of 45 (1 / m) and viscous resistance of 3e9 (1 /m^2).

Packed Bed Results
At the end of the simulation, we can see that a high-pressure drop has occurred in the porous area. The amount of pressure drop is directly related to the magnitude of the defined viscous and inertial resistances. To overcome this high-pressure drop, we must provide the pressure required to cross this barrier in the path before the gas enters the packed bed area using a pressure-boosting element such as a compressor.
