Recent research has highlighted the need for including realistic power take-off (PTO) model for oscillating water column (OWC) devices, including proper turbine modeling. In this work, a single-phase SPH-based method is presented to simulate the effect of varying air pressure on water free surface in a OWC chamber, herein referred to as “chamber model”. It is developed in the Lagrangian software DualSPHysics, which has a plug&play software interface to host external formulation that can account for turbine models. As for PTO modeling within this implementation, the turbine blades rotational speed has been included by mimicking a tunable diaphragm. Moreover, to step up its practical interest, the presented chamber model features both compressible and incompressible behavior.

Abstract
Recent research has highlighted the need for including realistic power take-off (PTO) model for oscillating water column (OWC) devices, including proper turbine modeling. In this work, a single-phase SPH-based method is presented to simulate the effect of varying air pressure on water free surface in a OWC chamber, herein referred to as “chamber model”. It is developed in the Lagrangian software DualSPHysics, which has a plug&play software interface to host external formulation that can account for turbine models. As for PTO modeling within this implementation, the turbine blades rotational speed has been included by mimicking a tunable diaphragm. Moreover, to step up its practical interest, the presented chamber model features both compressible and incompressible behavior.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
