Abstract—In this paper the acoustic pressure analysis in a thick-walled hollow cylinder similar to a solid propellant rocket motor with non-uniform port geometry is carried out for meeting the requirements of various types of canister designs for industrial applications. Parametric studies have been carried out with different port geometries with different ranges of frequency (1- 4000 Hz) without impedance and volumetric drag. The effects of pressure fluctuations on the thick walls of the canister at the steady state conditions are discussed. We have shown that the concept of volumetric dilatation in deriving the acoustic pressure governing equations can be replaced by a simple elemental approach. 

Index Terms—acoustic pressure, Solid Rocket Motor, thick walled Canister.
