Need a book referance

Hello,

I am badly in need a reference to study about Wigley hull. Can you suggest me any books for it?

 

What information do you need? Or do you need a book to list as a reference?

 

Thanks for your reply. Actually, I wanna know about Wigley hull, it's equation etc.

 

A gentleman called Wigley wrote a paper about bulbous bows - it is mentioned in this Wiki reference.
Bulbous bow - Wikipedia https://en.wikipedia.org/wiki/Bulbous_bow
Is this what you have in mind?

And in this link -
https://www.caeses.com/forum/index.php?/topic/117-wigley-hull/
is mentioned this formula -


Is this the equation you are referring to?

 

Thank you for your answer.

I am asking about the second one.

 

The Wigley hull was used to study the effect of hull shape on wave making. The original "Wigley" hull was just a square cornered wedge leading (on one model this was 5.81 ft long), a PMB section (4.38 ft long by 1.5 ft beam), and a similar wedge trailing (total 16 ft L x 1.5 ft B and 1 ft T) so as to generate distinct breast and quarter waves. The second "Wigley" hull mentioned in the formula was used to ease the generation of dipole bodies (i.e. sources and sinks) by Wigley and Havelock. Remember this was in the 1930's through to the 1950's so all the "calculated" profiles were done by hand.

See THE COLLECTED PAPERS OF SIR THOMAS HAVELOCK ON HYDRODYNAMICS , by Wigley, W. C. S., ONR/ACR-103, 1963

Edit to check size of tow model and list my sources.

 

Thanks, Have you any study material regrading this? I want detailed info about Wigley Hull.

 

See the above listed document.

 

Thank you very much

 

For the Wigley hull itself see THE APPROXIMATE CALCULATION OF WAVE RESISTANCE AT HIGH SPEED, page 500 of the collection which references this

Calculated and Measured Wave Resistance of a Series of Forms Defined Algebraically, the Prismatic Coefficient and Angle of Entrance Being Varied Independently https://books.google.com/books/about/Calculated_and_Measured_Wave_Resistance.html?id=D3SAnQAACAAJ

But there is a huge amount in ONR/ACR - 103 that lays the groundwork for those two papers.
