Study of the Suitability between Artificial Cavity and Traffic Vessel

Abstract:

The use of air cavities beneath ship hulls can lead to significant drag reduction. A study of air-ventilated cavities under a traffic vessel with flat bottom has been undertaken based on solving the RANS equations and VOF multiphase model. Macroscopic features in the air-cavity flow are predicted. Why the existing cavity form leads to unsatisfactory results on the traffic vessel is analyzed. The influence of parameters of artificial cavity on air cavity patterns is parametrically studied. Suggestions on improving cavity parameters and a new cavity form that can obtain stable air cavity are given, which may provide reference for the design of air cavity traffic vessels.
