Abstract
In this research perforated finned heat exchangersdiameter affected convective heat transmission. These holes were positioned on the circular fins so that they lined up with one another at the same predetermined angle. On the bottom of the fin, close to the heating tube surface, the perforations produced turbulence. The impact of this turbulence on pressure drop and heat transmission was then examined through a number of investigations. To ascertain the optimal heat transmission, several experiments were conducted at various diameters. In addition, a perforated finned heater was compared with an imperforate finned heater to observe the differences. In the cases of the Re above the critical value, Nusselt numbers for the perforated finned positions are higher than the Nusselt numbers for the imperforate state. Moreover, a correlation has been obtained between the Re and Nu in the Re number above the critical value and the Re below the critical value. Meanwhile, correlations regarding pressure drops in the flow areas have been obtained.
