| Abstract: | A non-1inear finite element (FE) model for describing the temperature field of vacuum aluminium brazing furnace was developed on the basis of considering the effect of nonlinear factors, such as thermal radiation and temperature-dependent properties of material.The temperature field of horizontal vacuum aluminium brazing furnace was calculated by finite element software ICEPAK & FLUENT.The uniformity of furnace temperature was validated,The numerical simulation of model and testing experiment was completed.... |
