This paper assesses the use of computational fluid dynamics (CFD) to model the ventilation of a working marine vessel, its performance in extreme climates, and potential improvements to the ventilation system which could lead to increased efficiencies of the engine and generator set.Comparisons between data gathered on the marine vessel and the computational model show good agreement, with an average discrepancy in temperature of 0.4%. The model showed that the current ventilation system was inadequate for the use of the marine vessel in Arctic waters. In contrast, the model showed the vessel was suited for tropical waters, and that the boat complied with British Standards for ventilation.Directing the flow within the engine room was found to improve the overall cooling of the room, and reduce the range of temperatures to improve thermal comfort. Directing the flow has shown reduced intake temperatures of the engine and generator set, improving efficiencies by 0.5% and 0.57% respectively. This paper demonstrates that the use of CFD to model marine vessel engine rooms can be used in retrospective design of ventilation systems, furthermore, it can be a tool utilised in the design stages for optimised engine rooms ventilation systems.
Detailed investigation of the applicability of CFD methodologies to a subject area with high industrial relevance. Good journal IF (2.74) Detailed computational study of thermal profiling by CFD, could be extended to improve design (or change BS) for marine vessels using recommendations therein. Interesting and complete demonstration of technique (on niche sample) and should be oft-cited as such by group and elsewhere.Originality: 10 Rigor: 10 Significance: 7 If 2.62, 0 citations, co collaboration
