RESISTANCE CHARACTERISTICS AND FORM FACTOR EVALUATION FOR GEOSIM MODELS OF KVLCC2 AND KCS

Abstract

Resistance characteristics and form factor were analyzed based on the ITTC 1957 model- ship correlation line and ATTC friction line to investigate the scale effect on the form factor. Considerable scale effects were found in resistance characteristics and consequently in the form factor for differently scaled geosim models. Importance of the friction line for the form factor evaluation and dependency of the form factor on Reynolds number were discussed. CFD computations were also performed for the corresponding geosim models by WAVIS 2.2. Resistance and flow characteristics for geosim models were investigated based on the CFD computations.
