Abstract
The interaction between an initially laminar boundary layer developing spatially on a flat plate and wakes traversing the inlet periodically has been simulated numerically. The three-dimensional, time-dependent Navier–Stokes equations were solved with 5.24×107 grid points using a message passing interface on a scalable parallel computer. The flow bears a close resemblance to the transitional boundary layer on turbomachinery blades and was designed following, in outline, the experiments by Liu & Rodi (1991). The momentum thickness Reynolds number evolves from Re[theta] = 80 to 1120. Mean and second-order statistics downstream of Re[theta] = 800 are of canonical flat-plate turbulent boundary layers and are in good agreement with Spalart (1988).
