In the present study, the numerical solution of the Ansys Fluent software has been used to
calculate the sound produced by the high-speed flow on a cylinder using the Lighthill
acoustic analogy. The calculations were carried out on a cylinder (part of the landing gear)
at a speed of 70 m/s (take-off and landing speeds of airliners). The problem is initially caried
out as a regular unsteady numerical solution. During the solution, aerodynamic noise data
sources are stored as inputs of acoustic analyzes in files. Then, by solving the acoustic …
