    Abstract

    Recycling techniques can be susceptive to nonphysical interaction between the downstream recycle plane and the inlet plane. Another issue alluded to in the literature is that the initial conditions proposed by LWS are insufficient for the effective initialization of turbulent flow. Several issues related to the implementation of the recycling method were explored, including spurious periodicity and error accumulation in recycled inflow simulations. The initial conditions in the recycled inflow simulation were also discussed. It was demonstrated that simple modification to the original conditions used in LWS is sufficient to correctly initialize turbulent flow, without recourse to the more complicated initialization schemes proposed in previous studies.
