Finite-amplitude standing waves in optimized acoustic resonators
Original language description
he paper deals with optimization of the shape of an axisymme tric acoustic resonator in order that acoustic pressure were maximized at one of its ends. In c omparison to the previously pub- lished studies, the resonator shape description is not rest ricted to an elementary function, it is rather described using a set of control points interconnect ed with splines allowing a wide vari- ety of possible shapes. In the first approximation, acoustic field in a shaped cavity is described using the quasi-one-dimensional Webster?s equation suppl emented with a term accounting for thermoviscous attenuation. A heuristic algorithm based on Evolution strategies is proposed for determination of the control points positions resultin g in maximum acoustic pressure inthe case of a piston or shaker driving of the resonator cavity . Numerical simulations show that the optimum shapes differ for individual methods of driving , they are rather simple, differ from the previously proposed shapes and possess
