pressure drop multiplier

Chemical Engineering

单词	pressure drop multiplier
释义	pressure drop multiplier Chemical Engineering A parameter used in two-phase gas–liquid frictional pressure drop calculations where the overall pressure drop along a length of pipe is due to contributions from the flowing gas and liquid. That is: $\frac{d p_{f}}{d z} = φ_{g}^{2} {(\frac{d p_{g}}{d z})}_{g} = φ_{L}^{2} {(\frac{d p_{L}}{d z})}_{L}$ where $φ_{g}^{2}$ and $φ_{L}^{2}$ are the pressure drop multipliers for the liquid and gas phases in which the parameter X² is defined as: $X^{2} = \frac{{(\frac{d p_{L}}{d z})}_{L}}{{(\frac{d p_{g}}{d z})}_{g}} = \frac{φ_{g}^{2}}{φ_{L}^{2}}$ Correlations have been developed to determine relationships for the multipliers for combinations of laminar and turbulent gas and liquid phases.
