Abstract: Rising fuel prices and inefficient fishing gear are hampering the fishing industry. In this paper, we present a computational fluid dynamic (CFD) model to analyse the hydrodynamic performance of trawl-doors, which are a major contributor to the high fuel consumption of fishing vessels. Furthermore, we couple the CFD model with an efficient design optimization technique and demonstrate how to redesign the trawl-door shapes for minimum drag at a given lift. The optimization techinique is surrogate-based and employs a coarse discritization CFD model with relaxed convergence criteria. The surrogate model is constructed using the physics based low-fidelity model and space mapping. The CFD model is applied to the analysis of current trawl-door shapes and reveals that they are operated at low efficiency (with lift-to-drag ratios lower than 1), mainly due to massively separated flow. An example design optimization case study reveals that the angle of attack can be reduced significantly by re -positioning and tilting the leading-edge slats. The performance can be improved by as much as 24 times (attaining lift-ro-drag ratios around 24). (More)
