“…Therefore, it is known as Direct Numerical Simulation. It was developed by this research group (BERGAMO, 2014;MARTINEZ;MEDEIROS, 2016;MATHIAS;MEDEIROS, 2018). In DNS, the primitive variables of Eq.…”

“…The subsequent sections explain in detail the numerical methodology used. For more details of the DNS scheme, the reader is refereed to Martinez and Medeiros (2016) and Mathias and Medeiros (2018) 3.4.1 Spatial derivatives Finite differences calculate the spatial derivatives according to the sixth-order spectral scheme described by Lele (1992). An advantage of the spectral scheme is the better approximation of the flow derivative for a broader spectrum of frequencies.…”
