    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
