Abstract:

Fluid-structure coupling finite element model is proposed to analysis the dynamic response of leaching tube in the construction of salt cavern gas storage. The stress and deformation of leaching tube induced by the carrying fluid flow are studied. Meanwhile, an experiment on the dynamic response of plastic tube caused by carrying fluid flow is carried out to verify the calculation accuracy of the proposed model. Experimental results prove that the finite element model proposed in the study has a high accuracy, which can well characterize the stress and deformation of leaching tube under the action of fluid flow. The errors between experimental and numerical results are about 5%, which can satisfy the engineering accuracy demands. Excited pressure produced by fluid flow has significant effects on the stress and deformation of leaching tube string, which is the main cause of tube damage. Therefore, low injected freshwater velocity is proposed at the initial stage and then it is increased slowly. Moreover, rapidly opening or closing the valve should be avoided.
