Correlation-based transition model for swept-wing flow using the cross-flow reynolds number

Correlation-based transition model for swept-wing flow was investigated using the cross-flow (CF) Reynolds number. It was demonstrated that the three-dimensional boundary-layer velocity consisting of a chord-wise velocity (U) and a span-wise velocity (W) could also be decomposed along the direction of the in-viscous streamline and its perpendicular direction. Location of the upper and lower boundaries of the computational domain was adjusted to match the pressure distribution on the upper surface of the wing. The final pressure distribution in current cases is compared with the data obtained in the UWT experiments and free-air.
