Abstract EN
In this work , experimental investigation has been done for free-convection heat transfer from rectangular fins array on a heated horizontal base plate to surrounding air in the steady-state flow condition with rectangular notch portion effects.
Five cases of fins arrays have been employed .
One case without notch and other cases with rectangular notches for different percentages of aspect ratio area removal from fin .
The horizontal base plate has been heated with various electrical supplied power values.
Different number of fins and spacing have been used .
The effect of notches from fins on average convection heat transfer coefficient and average Nusselt number at constant aspect ratio of fin height to fin length and varying heat inputs to the heating element have been discussed .
The experimental results show that the performance of notched fins array in term of average convection heat transfer coefficient is 28% to 45% higher than unnotched fins array.
The present experimental results have been compared with previously works .
The results show a good a greement
