Radiation of a cylindrical shell near a thin plate

Acoustic radiation from a cylindrical source close to a rigid corner

“…Given the surface velocity distribution of each source (i.e., V α n are known), one can determine the unknown modal coefficients using (13) (i.e., from c = R −1 u). Subsequently, the acoustic modal pressures may readily be obtained from (11), and the radial component of the acoustic power flux vector (acoustic intensity) radiated per unit solid angle from each cylinder is found from [13]…”

“…In particular, for sound wave propagation in a multiplyconnected medium, there is an acoustical interaction between the surfaces due to cross scattering. Many researchers have studied the mutual interaction between cylindrical objects subjected to a primary acoustic field [1][2][3][4][5][6][7][8][9][10][11][12]. Acoustic interaction of two pulsating cylinders in an ideal fluid is considered in [4].…”

“…An exact solution based on the classical modal series method for the problem of radiation loading on a cylindrical source freely suspended in a fluid-filled cylindrical cavity with a permeable boundary has been developed in [9,10]. Acoustic radiation from a shell-encapsulated concentric cylindrical source in a semi-infinite acoustic medium is studied in [11]. Just recently, the problem of modal vibrations of an infinite cylinder in the vicinity of a rigid/resilient planar interface is solved in [12].…”
