A grid sensitivity study has been performed by Wang et al. [15] for a cold case setup, and the compared line plots of velocity magnitude and turbulence kinetic energy revealed minor differences.Additionally, the comparison of the spectra obtained at the same probe locations on the three grids demonstrated the applicability of the implicit LES approach. The numerical results of the global parameters were validated with experimental measurements within an error range of less than 2%. Further validation and verification has been summarized by Wang [24]. With engine-like hot boundary conditions, the velocities occurring in the exhaust port are higher. Nevertheless, the viscosity of the medium is increased
due to the higher temperatures. Thus, the resulting Reynolds numbers for the two case setups are similar. Further, the used solver has been successfully employed to simulate similar flows in engineering applications and has been validated with Particle Image Velocimetry (PIV) measurements and experimentally obtained performance measurements [25]
