Abstract:
A new
mathematical model of multiphase pump working process is proposed
according to the energy and mass equilibrium. On basis of this model,
simulated results are analyzed with focus on the relationship of
back-flow, differential pressure, power consumption and gas void
fraction. In order to verify the mathematical model, performance data of
a prototype multiphase pump are measured and the p-V diagram is
recorded. Evidently from the comparison between the simulation result
and experimental data, the model is certified to simulate successfully
the working process in twin screw multiphase pump.
