Piston JONSWAP Peak

lhanley222 · April 2023

Hi There,

Does anyone have any idea on how to make the the peak of the JONSWAP higher while maintaining wave parameters for an irregular piston motion? I am trying to roughly simulate some field results for my project, but the spectrum generated from the SPH piston has a much lower peak and more spread. I've looked at the discretization options but those do not change the shape of the spectrum. And I know that the Pierson Moskowitz should probably have an even lower peak. I'd like to look into using some wave coupling techniques in SPH but I think I don't have the time and want to keep things simple.

Thanks

@iarba27 can explain this better to you

Thanks Alex,

I was able to tune up the JONSWAP Peak Coefficient and got something closer to what I wanted. Maybe Corrado has more insight.
