HEAT TRANSFER ANALYSIS OF HEAT GENERATING WIRE USING FINITE ELEMENT METHOD

This paper describes the numerical results of the heat transfer from heat generating wire at different conditions by finite element method. The parametric effects on heat transfer were investigated. The varied parameters included ambient conditions, as well as the shape of the cross-section. The numerical results show that the type of the medium where the heat generating wire immerges has strong effects on the heatdissipation rate. As the size of the diameter the heat dissipation to the ambient is decreased. The effects of free convection conditions on the wire surface are also significant. However, the effect of the shape of the cross-section is not very strong. The results presented in this paper provide useful information for the application of heat generating wire
