TWO-DIMENTIONAL MODEL OF FLUID FLOW WITHIN CORROSION FATIGUE CRACK
腐蚀疲劳裂纹内溶液的两维运动模型

The velocity of flow may obviously affect the chemical and electrochemical conditions within a corrosion fatigue crack. A tow-dimensional model was developed according to the continuity equation and conservation of fluid flow. The velocity of flow within the crack with a single edge-notch geometry was obtained by solving the partial differential equations with analytic method. The flow state within the corrosion fatigue crack and the influence of other parameters on the flow velocity for compact tension specimen were discussed according to the model.
