Deviation Analysis of Temperature Distribution in Copper Bar Heat Conduction Process Experiments Against Numerical Calculations

In the process of heat transfer by conduction, besides quantities in form surface area, length or thickness rod, and temperature difference between ends rod value thermal conductivity, other factors also affect rate to one which is environmental factors. As long as flows from high low temperature, decrease not uniform at any time interval. This a sign influence ambient for each part material. Temperature observations were carried out experimentally an open environment laboratory then compared with results numerical calculations ideal condition conduction process. The Boltzmann transport equation induction on metal rods solved using finite differences explicit method obtain distribution. showed distribution pattern copper experiments. caused amount released into environment. higher observation point, greater atmosphere.
