Abstract

The paper presents general Lagrangian formulation for sloshing of inviscid fluid in 2D tanks under vertical and horizontal excitation. In the case of a rectangular tank a third-order asymptotic solution for resonant sloshing with a dominating mode is derived using the recursive technique introduced by Buldakov et al. (2006). The problem is also solved numerically using a fully nonlinear finite difference approximation. Both the Lagrangian recursive asymptotic model and the Lagrangian fully nonlinear solver are applied to a problem of high amplitude resonant Faraday waves. Results are compared with experiments of Bredmose et al. (2003) and demonstrate excellent agreement.
