What Is The Effect Of Thermal Conductivity On Fin Effectiveness?

What Is The Effect Of Thermal Conductivity On Fin Effectiveness? 10a-d shows that the fin efficiency decreases monotonically (for different thermal conductivity and at a constant heat transfer coefficient) with increasing thermogeo- metric parameter. Also, it shows the variation of fin efficiency with thermogeometric in longitudinal convecting fin with insu- lated tip. What affects fin
