| Abstract: |
In plasma spraying, a large temperature variation occurs inside the cathode-anode region and in the plasma jet. Therefore, property variation with respect to the temperature has to be included. The transport properties such as viscosity, specific heat, and thermal conductivity were entered as function of temperature. These values had been incorporated in Fluent as linear piecewise profiles with respect to temperature and permitted the determination of these properties for the cell temperature obtained at every iteration. Another method has been used in this study, which is UDF (user defined function) file in a C++ language includes the properties of the argon plasma. The UDF file was compiled first then uploaded to FLUENT to start the solution process of the plasma jet flow. The correlation between the two methods will be discussed.
