Effect of Monohull Type and Catamaran Hull Type on Ocean Waste Collection Behavior Using OpenFOAM

Ocean waste that continues moving in the water has been a problem until now. This stimulated marine debris cleaning technology to emerge. research sought evaluate effectiveness of collection using monohull and catamaran fitted with forward conveyor. The Reynolds Average Navier Stokes (RANS)-based numerical simulation is used predict flow pattern characteristics, velocity contour, wave pattern, pressure distribution, ship resistance. current focuses on impact round-bilge-type inner flat-type hull front shape behavior by applying methods. multiphase solver configuration supplied OpenFOAM v2112 verified validated Delft 372 Froude numbers 0.3. effect free surface resistance characteristics was evaluated comparing these two models. results show due both flows much more conveniently through conveyor model than model. In addition, considering front-side flow, superior since able approach easily. However, faster at bringing closer conveyor, particularly location
