Determinat ion of Temperature Distribution Around a Moving Heat Source

Abstract

In this paper, the temperature distribution around a
moving heat source had been investigated including the
phase change and non phase change .
In non-phase change state, the governing equation
was converted to finite difference equation by finite
volume method and the equation was solved by
alternating direction implicit method. This method was
unconditionally stable .
In phase change state, the problem was formulated by
enthalpy function and finite difference equation was
solved with the explicit method because of the stability
criteria.
The effect of source heat, source velocity, preheat
temperature, variable physical properties, on
temperature distribution were examined, also their effect
on melting pool width and heat affected zone were
investigated. The application of these concepts in industry
was explained
