A Simplified Panel Method (sPM) for Hydrodynamics of Air Cushion Assisted Platforms

Air-cushion-assisted platforms (ACAPs) are floating supported by both buoyancy pontoon and air cushion, which have merits of wave bending moment reduction, better stability, hydrodynamic performance. However, there is barely a concise method that can quickly predict the motion response ACAPs. In this paper, simplified panel (sPM) was presented for evaluating hydrodynamics The sPM extends conventional boundary integral equation (BIE) to include radiation solutions pulsating pressure but ignores some unimportant air-water cross terms in equations whose coefficients cannot be directly derived from Green’s function methods. effectiveness validated experimental data an ACAP model with one chamber analytical results oscillating water column (OWC). numerical demonstrate give desirable predictions responses inner OWC as compared literature, suggests could approximately applied evaluation performance ACAPs OWCs.
