Stability Analysis of Gas Solids Flow through Parallel Paths

The core point for gas solids flow through parallel paths is to ensure the stability of desirable gas solids distribution, especially when each path is non-identical. In this study, a framework for studying the effect of non-identity on the stability of gas solids distribution is established. After introduce of a parameter, i.e. δ = (C_d2 – C_d1)/C_d2, reflecting of deviation from identity, the criterion, based on the concavity of total pressure drop surface, for detecting instability of gas-solid distribution through parallel system with non-identical paths is developed. Moreover, experimental studies are also carried out to verify the theoretical analysis.
