- W2348825832 abstract "To study the pressure pulsation caused by the interference between the rotating and static portion,i.e.an impeller and a volute in a high speed portion flow division pump by using the S-A turbulent flow equation and sliding grid technology in software Fluent 6.3,a straight impeller and a complex one were chosen respectively.An unsteady numerical simulation was performed at the design operating point to analyze the total pressure and static pressure distribution chart in the middle section.It has been found that the total pressure of the complex straight impeller is higher than that of the straight impeller but their static pressures are close.4 monitoring points were arranged at the circumferential locations of 0°,90°,180° and 270° of the inner volute wall at the outlet.A comparison of the total pressure pulsations shows that the peak values of the complex impeller are conspicuously higher than those of the straight one and the fluctuation amplitude between the peaks,however,is smaller than that of the straight one." @default.
