THE INTERACTION MECHANICAL RADIATION IMPEDANCE BETWEEN TWO PISTONS ARBITRARILY ORIENTED IN SPACE WITHOUT A BAFFLE

Abstract

Two pistons with enclosed backs located on the imaginary surface of a geometric sphere and generating sound in a coupling fluid medium interact with each other mechanically. Neglecting scattering effects, and restricting the analysis to the evaluation of the acoustic pressure over the second piston face due to the motion of the first piston, an equation is derived for the interaction mechanical radiation impedance coefficient between these two pistons without baffles. The derived formula is compared with the known formula for the interaction impedance between two pistons in a rigid spherical baffle. Although the derived formula is in the form of an infinite series, no actual numerical computation is performed because of the complexity of the terms in the series. (Author)
