- •
10° oblique fins provides the least effective heat transfer, followed by 30° and 50°.
- •
Heat transfer coefficient increases with oblique angles from 10° to 50°.
- •
Increment in oblique angles from 10° to 30° increases pressure drop.
- •
Pressure drop is almost negligible when oblique angle is increased from 30° to 50°.
- •
Instabilities for the oblique fins are reduced compared to the straight fins.
- •
10° oblique fins has the highest FOM. Interestingly, 30° and 50° have comparable FOM.
