Volute eccentricity effect on transient dynamic characteristics of nuclear main pump

WANG Peng;YUAN Shou-qi;WANG Xiu-li;ZHOU Bang-lun;LU Jia-xing;National Research Center of Pumps,Jiangsu University;  
In order to study the transient dynamic characteristics of a nuclear main pump under different conditions,the pressure fluctuation under four different volute eccentricities were analyzed based on the RNG k-ε model by using CFX three-dimensional unsteady numerical simulation methods. The results show that the change of eccentricity does not alter the dominant frequency of impeller,however,with the increasing of eccentricity,the pressure amplitude inside the impeller decreases first and then increases. The pressure has a similar changing trend for different eccentricities under different working conditions and the wave frequency is just equal to the number of guide vanes which indicates that the flow state inside the impeller is greatly influencd by guide vanes. Under small flow conditions,with the increase of eccentricity the peak of pressure fluctuation amplitude gradually delays to appear and the amplitude difference of the pressure fluctuation becomes larger under different eccentricities. Under the design working conditions,the fluctuation in the impeller flow passage is less than that under small flow conditions and the pressure amplitude at outlet is greater than at inlet. Under large flow rates,at monitor points,the pressure amplitudes within the impeller under different eccentricities from inlet to outlet are unstable,and the fluctuation amplitudes are greater than under the design conditions. The analysis results show that the pressure fluctuation of nuclear main pump under various operating conditions reaches its minimal when the eccentricity is within 10 ~ 15 mm.
