Thermal performance of pin-fin heat sink subject in magnetic field inside rectangular channels

The performance factor of the pin-fin inserts for both inline and staggered is evaluated. Comparison with the previous work shows good agreement. A correlation that best fits the experimental data is developed to predict the Nusselt number with presence of the magnetic field for pin-fin array inserts. The duct with staggered arrangement of fins produces a higher value of the heat transfer coefficient compared to in-line arrangement at all range of Reynolds number.
