A block-structured adaptive mesh refinement (AMR) method is applied to the problem of computing acoustic radiation from an aeroengine intake. The aim is to improve the efficiency of the computation through reduction of computational cells. A parallel implementation of the adaptive mesh refinement algorithm is achieved using message passing interface. It combines a range of 2nd- and 4th-order spatial stencils, a 4th-order low-dissipation and low-dispersion Runge-Kutta scheme for time integration and several different interpolation methods. To solve the problem of acoustic radiation from an aeroengine intake, the code is extended to support body-fitted grid structures. The problem of acoustic radiation is solved with linearised Euler equations. The results demonstrate the efficiency of the current adaptive mesh refinement algorithm.
