Analysis of dam-reservoir interaction by using homotopy analysis method

In this paper, dam-reservoir interaction for a vibrating structure in an unbounded and incompressible and inviscid fluid is analyzed by using homotopy analysis method. In the derivation of the hydrodynamic pressure variable, it is assumed that vibration of dam is in the normal direction of dam-reservoir interface and this interface is vertical. Moreover, bottom of fluid is rigid and horizontal. The results are compared with finite element method and analytical ones. It is seen that the results are efficient and gives better values than the previous published results and this method can be extendable for compressible fluid domains.
