- 論文の詳細を見る
Measurement of gas flow rate in gas-solids two-phase flow is studied both theoretically and experimentally by use of a horizontal diffuser. Since the pressure recovery in the diffuser varies with both the solid flow rate and diffuser length, the gas flow rate measured by the diffuser generally has some error. The relative error for the measurements is a monotone-increasing function of the measuring length, but never exceeds the value of the mass flow ratio. It is also shown that there is a length at which the error vanishes. This length can be estimated using an analytical equation. The effects of powder properties on the magnitude of the error are also discussed in detail.
