The internal diameter of the tubes and the bends was 0.01905 m, radius of curvature (mm) is 0.06 ≤ Rb ≤ 0.20, water flow rate Ql · 10−4(m3/s) is 2.000 to 4.65 and air flow rate is Qg · 10−5(m3/s) is 5.936 to 56.1189. Numerical modeling is carried using Fluent 6.3 software to find its applicability. The CFD simulations are carried out using mixture k−ε model for air-water flow through different U-bends. We are using k−ε model as the water flow through the bend is in turbulent condition. The simulated results predicts the flow structure, cell Reynolds number, static pressure, shear stress, shear strain, turbulent kinetic energy, turbulent intensity, dissipation losses, vorticity, helicity and volume fraction for two-phases. The CFD results show the very good agreement with the experimental values. PB Begell House LK https://www.dl.begellhouse.com/journals/71cb29ca5b40f8f8,4e710fe64640d4af,5dcd59622143dd05.html
