- •
Spontaneous heat transfer rates (q) for various flow systems are investigated.
- •
Three interesting heat-transfer-coefficient (h) regimes are identified.
- •
The Galerkin finite element method is used for simulations.
- •
In regime I, q decreases as h increases, defying our physical intuition.
