Abstract

NUMERICAL simulations of turbulent boundary layers require inflow/outflow boundary conditions. Downstream flow is particularly sensitive to the inlet boundary condition; it is necessary to provide a realistic, coherent series of time-varying velocity components to avoid wasteful and potentially costly readjustment behavior. Simple periodic boundary conditions (where downstream flow is reapplied at the inlet), while suitable for channel or pipe flow simulations, are poorly suited to spatially developing flows such as flat-plate boundary layers [1]. Lund et al. [2] (LWS) developed a quasi-periodic approach using an accurate scaling technique. This method used recycling of the downstream data to provide the inlet boundary condition on the inflow simulation (illustrated in Fig. 1). It has been successfully applied in both incompressible and compressible boundary-layer simulations [3–5]. Despite the wealth of publications that have successfully applied this method, a number of studies [5–10] have indicated that some aspects of LWS method can prove difficult to implement. Hurdles include spurious periodicity, error accumulation, and initial conditions. The main objective of this Technical Note is to propose simple modification to the original LWS formulation to address these issues, and also to avoid use of the 99% boundary-layer thickness.
