- •
Slot jet of air on a finned cylinder is a compound technique to enhance heat transfer.
- •
Numerical simulations are done with two-equation turbulent models (RNG k–ɛ and SST k–ω).
- •
Radial fins have a rectangular profile with a fixed total volume as constrain.
- •
Maximum heat transfer is at the minimum slot to cylinder distance.
- •
Maximum heat transfer is at the maximum fin spacing to fin height ratio.
