PENENTUAN LAJU DISTRIBUSI SUHU DAN ENERGI PANAS PADA SEBUAH BALOK BESI MENGGUNAKAN PENDEKATAN DIFFUTION EQUATIONDENGAN DEFINITE ELEMENT METHOD

Abstract

In research it distribusion of temperature and callor can formulate in space 4x3x5 cm using diffusion equation. The diffusion equation can build form conductivity and callor equation by using technical separation variable and subtitusion can be built discreat formulation ,,, 4321 ),,,( tzyxH nnnn ,,, 4321 ),,,( tzyxT nnnn . The distribusion of tempe-rature and callor have fourth factor hot spreadthas special in iron (Fe); thermal conductivities k , kinds callor c , density of mass besi  , anomaly of material iron.This research distribusion of temperature and callor can be drawn by MATLAB program with besi definite element method. The result of visualization distribusion of temperature and callor with different energy level(1,3,2,3), (3,5,6,5), (5,7,9,6), (7,9,8,6), and (9,7,5,9). If the energy level is small the color of visualization become red because it’s near with hot source and the the color of visualization become greenbecause it’s far with hot source. Actually lost degradation of color in drawing of iron asresult fromdistribusiontemperature and callor in iron material.The quantities callor is brought by temperature in ironmaterial.
