An Attempt to Detect the Importance of Turbulent Boundary Layer in Ship Wave Resistance,

Abstract

The Reynolds number of a ship model is increased artificially by using a flat plate leading the model. The turbulence level of the flat plate boundary layer is also altered. A decrease in the calculated wave resistance and measured residual resistance is observed within the Froude number range .2 less than Fr less than .4. The results indicate a viscous wave interaction which can be formulated in terms of the visco elastic properties of turbulent flow. A possible formulation using this procedure is also indicated.
