A study on slug induced stresses using file-based coupling technique

Cyclic stresses imposed on the piping system are the potential cause of severe fatigue damage and failure. These stresses are induced due to pressure fluctuations which occurred as result of the slug flow motion inside the pipe. In this study, a coupled Fluid-Structure Interaction approach based on...
