Thoretical Calculation
Michell
Determine flow around hull
Resistance
Determine normal pressure distribution
Assumptions
Non viscous fluid
Hull is narrow
waves small height
No sinkage or trim
Havelock
Calculate wave pattern
at a great distance astern
Resistance
energy necessary
maintain wave system
method
Sources
Forebody
Sinks
Afterbody
Sum of total strength is zero
ONLY wavemaking Resistance
Non-viscous fluid
assumption
non viscous fluid
ISOLATE WAVEMAKING RESISTANCE
Daube
Non-linear calculations
Prof Inui
Fr BTW 0,1 and 0,35
Geometry at ENDS most important
Quando a CINDERELA fica na frente do SOL, a BUNDA é bem importante
High speed
distribution of sources along hull
becomes important
Reduced resistance with BULB (Stem and Stern)
Combination of Mathematical and Experimental
