- •
Two-inlet cooling structure is introduced for trailing edge cooling channel.
- •
The parabolic relations between MR and overall averaged Nu ratios are correlated.
- •
Two-inlet inflow reduces rotational effect on trailing-to-leading heat transfer difference.
- •
A critical MR is observed in rotating channel to determine low-radius leading heat transfer.
- •
The coupling effect of rotation and MR dominates rotational heat transfer distribution.
