Varieties of research on
turbulent-induced noise are conducted with combinations of acoustic analogy
methods and computational fluid dynamic methods to analyse efficiently and
accurately. Application of FW-H acoustic analogy without turbulent noise is the
most popular method due to its calculation cost. In this paper,
turbulent-induced noise is predicted using RANS turbulence model and permeable
FW-H method. For simplicity, noise from 2D cylinder is examined using three
different methods: direct method of RANS, FW-H method without turbulent noise
and permeable FW-H method which can take into account of turbulent-induced
noise. Turbulent noise was well predicted using permeable FW-H method with same
computational cost of original FW-H method. Also, ability of permeable FW-H method
to predict highly accurate turbulent-induced noise by applying adequate
permeable surface is presented. The procedure to predict turbulent- induced
noise using permeable FW-H is established and its usability is shown.
