文摘

The failure of three-way injecting water pipe can be attributed to the flow corrosion–erosion. A large velocity gradient results in a region of low flow velocity, high wall shear stress and high turbulent kinetic energy. This gradient also makes the non-uniformity coefficient of velocity high. The high risk area from the CFD simulation coincides with the breakage area of the three-way pipe on the spot.
