Abstract
In the mixer,cold and hot water mixed uneven will not lead to constant water temperature. The simulation analysis of the water mixers internal physics field can optimize the structure of the water mixer and make it more efficient in engineering application,thus reducing energy consumption. The paper simulates internal three-dimensional flow and heat transfer characteristics on the the cold and hot water mixer based on RNG k -εturbulence model in Fluent software,and elaborates the influence of entrance position on its internal physics field and mixing effect through the analysis of mixers'internal temperature field and pressure.The results show that when the inlet velocity is smaller than 0.1 m/s,the temperature distribution of three kinds of models is close.With the increase of flow velocity,the outlet temperature of the cold and hot water horizontal tangential flows into the model one and model two is more constant,and the outlet water temperature is constant,which tends to 300K,while the temperature of the hot and cold water flows from the upper side of the model three is not constant.Among the three models,the mixed effect of model one is the best,but that of model three is the worst.关键词
