To verify the applicability of UTCart (a compressible flow solver based on the hierarchical Cartesian grid method) to high Reynolds number flows, a flow field analysis around a commercial airliner at cruise was conducted. The analysis is performed in the range of Reynolds number from that in general wind tunnel tests to the flight Reynolds number, and the reproducibility of the Reynolds number effect is verified through comparison with the results in the high Reynolds number wind tunnel tests. The simulations were able to reproduce the Reynolds number effects (lift coefficient increase and drag coefficient decrease, etc.) observed in the wind tunnel tests.
