Porous materials are commonly used in various industrial systems such as ducts, HVAC, hoods, mufflers, in order to introduce acoustic absorption and to reduce the radiated acoustics levels. For problems involving flow-induced noise mechanisms and exp

A surface based lattice Boltzmann impedance boundary condition (BC) using Ozyoruk’s model [J. Comput. Phys., 146 (1998), pp. 29-57] is proposed and implemented in PowerFLOW. In Ozyoruk’s model, pressure fluctuation is directly linked to normal ve

The role of surfaces in the mechanism of sound generation by low Mach number flows interacting with solid nonvibrating surfaces is well established by the classical aeroacoustic papers by Powell, Doak, Ffowcs Williams, Crighton, or Howe. It can be fo
