NUMERICAL ANALYSIS OF THE HEAT AND MASS TRANSFER PROCESS FOR TIG ARC

Abstract

Abstract: A perfect mathematical model is created to reveal heat and mass transfer process for the TIG arc, in which the Ohm law is used to calculate the current density distribution and the K-a model is adopted to resolve the complex turbulent flow problems. Numerical computation is made by means of a SUN workstation with FORTRAN language, thus the distribution of flow fields, temperature and current density is obtained. The computed results agree, yell with the important experiment results.

Key words: Heat and mass transfer, Numerical analysis, Stream distribution, Temperature distribution, Welding arc
