Pengukuran distribusi temperatur pada pelat logam menggunakan metode finite element

Abstract

To measure temperature in an object, we use temperature sensor. But what if the temperature which we are going to measure has many of nodes? Putting all sensors on that nodes is less efficient. Solution for this problem is reducing the quantity of sensors and put it on boundary system and use that for computation purpose. This research was using finite element method two-dimensional with triangular element. The output for this research is distribution of heat transfer on metal surface. This research measuring thermal conductivity metal plate in steady state problem in two-dimensional conductivity direction. The comparison between measurement with digital thermometer EXTECH and computational finite element method on node coordinate (21, 5.5) is 98.18%, node (21, 1.1) is 96.67%, node 28, 5.5) is 97.55%, node (21, 33.9) is 97.96%.
