Numerical Simulation of Scouring Erosion Characteristics for Electric Submersible Pump Impeller CHEN Si2,b, WANG Zun-ce1,a 1Northeast Petroleum University,Daqing,163318,China 2Northeast Petroleum University,Daqing,163318,China airaqiraq@126.com,bWangzc@nepu.edu.cn Keywords: Electric Submersible Pump; discrete phase model; particle impact erosion; Numerical simulation; Abstract.
This paper shows the numerical simulation of the problem that electrical submersible pump impeller is vulnerable to particle impact erosion in the water under the condition of the water injection of the same wells in oil field.
This simulation is based on Fluent of CFD software, which has built a geometric model of electric submersible pump impeller flow field, and given the calculation of the internal flow field of the impeller, and showed the solution of the motion track of the particles in the turbulent by the way of discrete phase model and random orbit, and calculated the erosion by the micro cutting model by particless, and compared the field test data with the simulation results which proved the reliability of numerical simulation method.
Numerical simulation assumption: the solid particles are spherical shape.
Then on the specific wear area both of the blade of the impeller and the whole area of the up shroud appear serious wear, which has a little difference from the outcome of the simulation.

Numerical simulations play an important role in investing the spread of fire and smoke[1-4].
Generally, there are two types of simulation method which are called as the zone models and the field, or Computational Fluid Dynamics(CFD) models.
Thus, the field model is considered to be a more accurate method dealing with fire simulation.
