Effect of crude oil viscosity on optimized parameters of ANSYS simulation model forfluid dynamic noise of oil transfer pump
In order to study the effect of crude oil viscosity on the optimization parameters of the ANSYS simulation model for hy-drodynamic noise of oil transfer pumps,and to reduce the simulation errors caused by the model parameters.In this paper,the ZA150-4400 oil transfer pump is taken as the research object,based on ANSYS simulation platform,the RNG k-εmodel is used to study the static pressure distribution characteristics of crude oil hydrodynamic noise,and the Smagorinsky-Lilly model in LES is used to study the dynamic distribution characteristics of crude oil hydrodynamic noise.According to the Cμ-parameter 0.0845 of water medi-um,a linear fitting relationship between crude oil viscosity μe and the modified parameter Cμ is constructed through a large number of simulation experiments of Cμ-parameter optimization under different crude oil viscosities μe.The results of simulation experiments show that the optimal parameter settings for different crude oil viscosities μe corresponding to Cμ have a maximum deviation of 0.61 Hz in the shaft frequency and 3.05 Hz in the impeller blade passing frequency in the dynamic characteristics simulation.
