Summary: In [Y. Achdou et al., J. Comput. Phys. 147, No. 1, 187–218 (1998; Zbl 0917.76013); J. D. Anderson jun., Hypersonic and high temperature gas dynamics. Reston, VA.: American Institute of Aeronautics and Astronautics (AIAA). (1989; doi:10.2514/4.861956)], a numerical scheme is developed to accurately capture the microscale effects of periodic spanwise roughness at essentially the cost of solving twice a laminar problem on a smooth domain at affordable resolution. In the present work, this methodology is extended to the turbulent regime modeled by the compressible Reynolds-averaged Navier-Stokes (RANS) equations using a one-equation model. As an application, a subsonic flow over a flat plate with partially embedded periodic roughness, i.e., riblets, is considered.
