How to calculate the pressure drop in powder gas transportation

1. Powder gas transportation falls under the category of gas-solid two-phase transportation; due to the presence of solid particles, the transportation process is closely related to the properties of these solids. It differs from dilute-phase and dense-phase transportation, and phenomena such as slippage and clogging can occur. 2. The pressure drop in gas-solid transportation pipelines consists of three components: the static pressure drop of the gas-solid slurry from the starting point to the ending point, the static pressure drop resulting from particle acceleration, and the frictional resistance associated with the gas-solid mixed flow. 3. Since gas-solid fluids with different proportions and properties have varying effects on resistance, many coefficients are required for correction during calculations. 4. This aspect is extensively covered in the field of fluidized catalytic cracking, and it can serve as a reference.
