 Full-scale CFD simulations of Air Lubrication with DIS-based Air Cavity for Planing Hull  MARINE 2023  Fabio De Luca1, Simone Mancini1*, Claudio Pensa1, Riccardo Pigazzini1, and Vincenzo Sorrentino1,2 1Università degli Studi di Napoli “Federico II” Dipartimento di Ingegneria Industriale Via Claudio 21, 80125 Naples, Italy  2Eurisco Consulting SRL Via Degli Artisti 9, 80059 Torre Del Greco, Italy  *Corresponding author: simone.mancini@unina.it  ABSTRACT The air lubrication system represents among the others one of the most promising solutions in the maritime industry to reduce fuel consumption and carbon emissions. However, this energy-saving solution is usually applied on displacement hulls where simulations, tests and trials have been largely investigated. The application of air lubrication systems on planing or semi-planing hulls is indeed not common, as those hulls are characterized by a different hydrodynamic behaviour that can influence the effectiveness of the air lubrication solution. In addition, full-scale analyses of this energy-saving technology are in general rather rare, in particular for its application on planing hulls. The current investigation is part of a wide experimental and numerical research campaign that aims to analyze the application of an air injection system where the air cavity is obtained by a DIS (Double Interceptor System) installed on the bottom of a planing hull [1]. The aim of the present study is to provide an insight into the potential scale effects of an air injection system combined with the DIS system on a planing hull through Computational Fluid Dynamics (CFD) simulations and how scale effects could impact the full-scale efficiency of this energy-saving technology application. The CFD simulations of the planing hull with DIS and air injection system have been carried out in model and full-scale. Model scale results are then compared against towing tank model tests.
