Abstract

In order to explore the flow characteristics in Horizontal Mutation Pipe, an SIMPLEC algorithm was used to simulate the flow field in horizontal mutation pipe by using the computational fluid dynamics software of Fluent. The variation of the length of entrance zone and the local resistance coefficient can be optimized by analyzing regulation of their effect on entrance velocity, the ratio of tube and the inclination angles. The results indicate that the re-attachment length relate to expansion ratio and inclination angles; the local loss coefficient increases with the increment of expansion ratio whereas decreases with the decrement of the inclination angles.
