摘要
Abstract
In order to explore the flow characteristics in horizontal mutation pipe, the SIMPLEC algorithm and the computational fluid dynamics software Fluent are used to make a numerical simulation on the mutation pipe. The effects of different entrance velocity, pipe diameter ratio and inclination angle on the reattachment length and local resistance coeffi-cient are analyzed. The results indicate that the reattachment length is related to expansion ratio and inclination angle; the local resistance coefficient increases with the increment of expansion ratio whereas decreases with the decrement of the inclination angle; The results reflect the essential characteristics of mutation pipe flow and provide a reference for solving the common problems in industrial production.关键词
