Numerical investigations on unsteady vortical flows and separation-induced transition over a cycloidal rotor at low Reynolds number

Analysis of flow-induced performance change of cycloidal rotors: Influence of pitching kinematic and chord-to-radius ratio

“…Some more details about the mesh are given in Table 2. The influence of the mesh resolution on the numerical results was discussed in our previous work [21] in the same configuration and the present setup was eventually validated, so it is used hereafter in the present paper.…”

“…The all y + wall treatment is used, and the maximal y + does not exceed 0.5 at any position in a revolution. The influence of the time-step, the level of convergence, and the inlet boundary conditions (turbulence intensity and eddy viscosity ratio), were discussed in our previous work [21] and the conclusions are used here to select these different parameters.…”
