Abstract :
In this work, analysis of transient three-dimensional heat
transfer in a slab with internal heat generation and heated
by a point moving heat source along its axis is carried out
using integral transforms methods. The heat input into slab
or workpiece by the moving heat source is considered in the
model. From the results, it was established that the
temperature of the material during the heat transfer process
decreases while the time required to reach the peak
temperature increases with increasing distance from the
centerline. Also, the rate of heating and the rate of cooling
decrease with increasing distance from the centerline. The
computed results at different monitoring locations show
typical features of the temperature profiles and they afford a
close analysis of the factors governing the heat flow in a
point moving heat source.
