摘　　要：通过水力学模拟试验对铸造铝合金过滤流动过程进行了分析 ,建立了过滤效率的水力学模拟试验关系式。结果表明 :在雷诺数一定的情况下 ,增大过滤器的孔隙率 ,则过滤效率增加 ;当过滤器的孔隙率一定 ,雷诺数减小时 。The analysis of filtering flow process of aluminum cast alloy based on hydraulic simulation was carried out. The filtering efficiency formula was established. The results showed that the filtering efficiency was improved with the increase of filter's porosity under constant Re number and with the decrease of Re value under constant filter's porosity .
