Engine nacelle air inlet with rough turbulator surface
By setting a turbulence generator surface on the internal flow surface of the nacelle air intake, laminar airflow is transformed into turbulent airflow, solving the problem of excessively high temperatures in certain sections of the nacelle air intake and achieving a more effective cooling effect.

AI Technical Summary
Certain sections of the cabin air intake may reach excessively high temperatures, and existing technologies are unable to effectively reduce these high temperatures, especially due to the boundary layer heat transfer effect of laminar airflow causing heat to be transferred downstream.
A turbulence generator surface is set on the internal flow surface of the air intake of the nacelle. By converting laminar airflow into turbulent airflow, the mixing of the boundary layer is enhanced to reduce the temperature. The turbulence generator surface can be a rough surface or a shot-peened surface, including dents and stripe structures.
By transforming laminar airflow into turbulent airflow, the mixing of the boundary layer is enhanced, effectively reducing the temperature of the downstream structure of the cabin air inlet, reducing heat transfer, and improving the cooling effect.
