| Abstract: | According to the free burning TIG arc,analysis and identify the concerning governing equations and boundary conditions,a two-dimensional steady axisymmetric model has been developed.The secondary development of Fluent with UDF,which is used to compile the governing equations and related source terms,realizes the steady-state TIG arc model and gains the data of temperature field,flow field,pressure field and surface pressure distribution of the workpiece.The results showed that Fluent can be convenient and efficient to simulate the TIG arc,the data obtained is in good agreement with measurements of related literature and has important meaning for welding research and production. |
