Abstract: Abstract We present in this work a new variational formulation by integral equations which enables the calculation of acoustic fields radiated in non uniform compressible flows. Indeed, this formulation reduces the integral domain without modifying the Sommerfeld’s radiation condition. Moreover it avoids computation of the “finite part” of singular integrals and leads to a compact symetrical linear system after discretisation by finite elements. This system is then solved by an iterative method.
