Transient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source

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.
