Analisis Konduktivitas Termal Material Logam Menggunakan Metode Searle

Abstract

Knowing the thermal conductivity of a material will help determine the suitable material for the desired function. However, in reality the available materials aren"™t measured so if the material subjected to material engineering such as heat treatment, needed a method to estimate the thermal conductivity value of the material. Searle method are method that used for measure thermal conductivity values on metal materials. This research aims to anatomize measurement result of coefficient thermal conductivity values of metal also compared it with references used. This study uses study literature methods and experimental methods. The literature method used to anatomize and determine heat transfer reference values for metallic materials. While the experimental method is used to create experiments tools and trials to obtain data. From the research, thermal conductivity values of copper metal and stainless steel obtained respectively 361,7085 W/m. °C and 14,4662 W/m. °C. There is a difference value conductivity thermal from Searle with reference because it"™s influenced by tool factor which isn"™t in adiabatic state also the materials haven"™t tested is it same with material on reference and deviation result from thermal conductivity copper and stainless steel with reference respectively 9.798 % and 4.329%. In the future, it is necessary to pay attention to the density level of the tool so that heat loss doesn"™t occur during the experiment to gain more accurate results. It is also necessary to pay attention to the level of accuracy of the measuring instruments used in order to reduce the difference rate in obtaining data.
