- •
A total of 55 experiments are conducted and used to validate the numerical model.
- •
Inter-fin base length influences optimal fin orientation and spacing of heat sinks.
- •
The thermal resistance is reduced up to 36.7% for same heat sink base area.
- •
Nusselt number correlations based on the numerical results are proposed.
- •
The findings of the study are useful for high-power LED lighting applications.
