Abstract

In this study, the resistance performances of barge are analyzed by model tests and computation using CFD to investigate the flow characteristics around a barge in still water. The model tests are carried out in infinite depth in Inha Technical College Circulation Tank to observe the resistance and the numerical simulations based on VOF(Volume of Fluid) method are performed to analyze the flow around the barge. We have selected two barge models to investigate the flow characteristics according to the different type of barges. The experiments are carried out with the models from 5kts to 10kts(designed speed 7kts) considering the effect of adverse and favorable current. The numerical simulations are performed to analyze the flow and resistance characteristics of barge in the full loaded condition with the target speed and compared with the experimental data to confirm the reliability of the numerical method. The result was that the difference of resistance with 25% occurred at low speed and EHP increased rapidly from 7kts.
