dependence of Wake fraction on ship speed,

[pavel915]

I am studyin on how ship speed affects the value of wake fraction. My concern is how the wake fraction w varies for diffrent speed of a ship , I need a good previous study or paper on this so that i can have a light upon this.
Please help my by giving some information or papers on it,
