Analysis of Internal Flow Field for Centrifugal Fan in Series
Centrifugal fan in series with high wind pressure is the key facility of pneumatic transport equipment.To consider the impact of changed conditions on performance of centrifugal fan,internal flow of three-stage centrifugal fan at rated speed in different total pressure conditions is analyzed by CFD software FLUENT6.3 in this paper.Flow characteristics are obtained and the differences of total pressure and velocity distribution in each impeller are analyzed under different conditions,velocity distribution on the meridian plane and section of wind guide plates are compared.Finally,curves of P-Q and P-η at 4600r/min are forecasted through the analysis of the data,which provide references for reducing impact that condition alteration on fan performance and improving the efficiency of the fan.
