“…All of the aforementioned studies make the assumption that thermal conductivity is either a constant or an exponential function of temperature, or linearly temperature-dependent [25]. Furthermore, the temperature distribution can be derived by a lengthy computation process using a variety of analytical and numerical techniques that have been used in numerous investigations [20][21][22][23][24][25][26]. Thus, the aim of this work is to offer a simple calculation-based solution for the temperature distribution of a longitudinal fin in both linear and non-linear cases and to demonstrate the effectiveness of the technique.…”
