...Relative to the Baseline grid, the Coarse grid was reduced by a factor of 2 in the number of grid point in both x and y directions and the Fine grid was generated by increasing the refinement in each (x and y) direction by a factor of two (Zhu et al. 2015)....

...The equivalent source terms under the integral sign are: Qi and Lij thickness and loading noise; Tij the Lighthill stress tensor.(16) Due to a low-Mach-number flow around the geometries, sound radiation from the quadrupole source (the last term in equation (3)) is neglected and Farassat’s Formulation 1A with an integral solver based on the retarded time approach was used to solve the FW–H equation....
