【摘要】T-shaped multi-limbed tubes separate oil and water according to their density ditference,having advantages of terseness,coherence and economy.The numericalsimulation of the flow velocity and phase distribution in T-shaped muhi-limbed tubes is conducted,and its results show that a higher mixture flow velocity is adverse to oil-water stable settlement among branch tubes,and the separation efficiency decreases with the increase of mixture flow velocity;the separation efficiency is related to the split ratio,the separation efficiency is relatively high in the split ratio narrow section that is the same as the inlet oil volume fraction (namely the oil volume fraction is 40% and the split ratio is 4:6),and to ensure the smooth implementation of the subsequent wastewater treatment process of T-shaped multi-limbed tubes,the split ratio of the oil-water outlet is recommended slightly larger than the theoretical value.The increase of branch tube number can change in diversity the oil-water flow direction in branch tubes,afford more diffluent branch channels for oil and water and promote circulation and separation.%T形多分支管依据油水的密度差异进行油水分离,具有集约、连续、经济等优点.对T形多分支管中的流速及相分布进行数值模拟,结果表明:较大的混合流速不利于油、
