As strongly accelerated boundary layers become thinner, the necessary mesh resolution coupled with the need for long computational domains, makes direct simulations challenging. Furthermore, the prescription of accurate turbulent inflow boundary conditions in spatially-developing boundary layers is not a trivial task. For that reason, the methodology proposed in [2] is employed in this investigation [1]. The method prescribes time-dependent turbulent information at the inlet plane based on the transformed flow solution downstream (mean flow and fluctuations) by using scaling laws from a downstream plane called recycle (rescaling-recycling approach [3]). There is no need to use an empirical correlation in order to compute the inlet friction velocity, such information is deduced dynamically by involving an additional plane, the so called test plane located between the inlet and recycle stations.
