  4. Abstract:
  5. In order to compare the frictional resistance of three kinds of ship’s hull coatings (foul release, SPC copper, SPC TBT) in the unfouled conditions, the numerical studies have been made. Simulations have been carried out for different Reynolds numbers in the range of 2.85 × 106-5.5 × 106 based on the plate length and flow velocity. Antifouling coatings have larger mean roughness than foul release. The results have indicated that frictional resistance coefficient of foul release test plate is lower than SPC copper and SPC TBT test plates. The total resistance obtained by computational fluid dynamics has been compared with the experimental data and its good agreement has proven the ability of CFD modeling in the calculation of fluid flow resistance, considering the coating characteristics
