... by defining perfectly matched layers at computational boundaries. A meticulous immersed boundary method is developed to represent the interface between an irregularly shaped solid and the Cartesian computational grid, improving the precision of the computed acoustic radiation force. Based on the proposed...

...-domain impedance boundary condition is reported and demonstrates the versatility of the computational model. computational aeroacoustics immersed boundary method acoustic scattering Scattering of sound can usually be viewed as a nonviscous process and acoustic quantities are governed...
