文摘
- •
Curved vortex generators show better thermo-hydraulic performance than plane ones.
- •
Punching holes at the surface of VGs can improve the thermo-hydraulic performance.
- •
The heat transfer mechanism of VGs with punched holes is clarified by FSP theory.
- •
The optimal ratio of hole area to VG area is 0.06 considering overall performance.
- •
Punching holes at lower position and close to leading edge gives better performance.
