- Author's Original
A non-linear pendulum model is developed to represent the motion of a sloshing fluid in real time. The forces imposed by the sloshing fluid are identified using multiphase RANS CFD simulations and subsequently included in the pendulum sloshing model. The pendulum sloshing model was used to simulate sloshing induced by linear and angular motions at and near resonance. Good agreement between the CFD data and the pendulum sloshing model was observed. A blind simulation with multiple surge excitation components is carried out and the pendulum sloshing model agrees with the RANS CFD result.
Typically, the computational time of the pendulum is approximately 1/700th of real time.
