... experiments and MST prediction is due to the effect of boundary-layer turbulence. However, difference is also observed at Reynolds numbers below which turbulence is expected in the nose region (40,000 < Re < 300,000). Therefore, we hypothesize that the difference in this range of Re may be attributed...
