Numerical study of hydrodynamic resistance on a sportive sprint hull

In this work we perform a numerical study on the flow around the hulls of competition kayaks with the aim of predicting accurate drag forces. The numerical simulations were first performed using the Wigley hull geometry, a typical validation case for flows around marine vessels. The total drag force...

Resumo:In this work we perform a numerical study on the flow around the hulls of competition kayaks with the aim of predicting accurate drag forces. The numerical simulations were first performed using the Wigley hull geometry, a typical validation case for flows around marine vessels. The total drag force and wave profiles of the hull were determined for different Froude numbers and compared with experimental measurements. After validation and verification of the numerical method, the flow around two competition sprint kayaks was investigated. The drag force was calculated and compared with experimental and numerical data
