Web2.2 Rayleigh Integral Formulation The Rayleigh integral formulation is used in the exterior region. In brief, it relates the velocity potential ϕ(p)at apointp in the exterior E,ontheopeningΠ,oronthe baffle to the normal velocity v on the opening Π. (Note that in the standard method the opening is a vibrating panel.) In the standard integral ...
