Assumung adding 3 complex vectrors (cvect1, cvect2 and cvect3).
What is the difference between using command:
CSQRT(cvect1**2+cvect2**2+cvect3**2)
and command:
CABS(cvect1+cvect2+cvect3)
??
The first one produces a complex vector (real and imaginary part), but the second only the real part has a...
The device's dimensions are:
Radius of the coaxial cylindrical body: 7m
Draught of the coaxial cylindrical body: 20m
Radius of the oscillating chamber: 14m
Thickness of the oscillating chamber: 1.5m
Draught of the oscillating chamber: 8m
Considered your suggestion for half closed air duct...
About natural resonance frequencies relevant articles are: Lateral sloshing in mooving containers by Sandor Silverman and Norman Abramson (where it is described how to obtain the natural frequencies of an open chamber OWC) and among others, Hydrodynamic analysis of three–unit arrays of floating...
The issue that we are facing is that when we plot the heave response as a function of the wave frequency, when the oscillating chamber is closed in the upper (no air is going out or in), we observe three maxima. The first is near 0.9 rad/s and it probably occurs due to the first anti-symmetric...
Homework Statement
Assuming that an OWC device is floating/moored in monochromatic waves. When there isn't air pressure distribution inside (atmospheric condition) the device behaves as an undambed body (with the oscillating chamber open to the atmosphere). When there is air pressure...
Assuming that a TLP platform is examined and the wave forces acting on the tendons of the mooring lines are presented in RAOs (as a function of wave frequency). Using Jonswap spectra for North sea (i.e peakness factor equal to 3.3) we can obtain Hs (significant wave height); Tp (peak period) and...
