چکیده انگلیسی
Interference effects between the dominant waves created by the bow and the stern of a monohull ship, of length L, that advances at constant speed V along a straight path in calm water of uniform finite depth D are considered. The largest waves due to constructive interference result in an apparent wake angle Ïmax that can differ greatly from the cusp or asymptote angles associated with the wave pattern of a ship when interference effects are ignored, as in Kelvin's classical analysis. Thus, wave interference has a very large effect on the wave signature of a ship in shallow water and cannot be ignored. Water-depth effects on the wake angle Ïmax are found to be insignificant for water depths dLâ¡D/L greater than ddeepLâ0.89 or for Froude numbers Fâ¡V/gL greater than Fdeepâ0.5/dL. Furthermore, the water depth dL has only a relatively small influence on the wake angle Ïmax for 1.5
