A Novel Approach to Model Moving Heat Sources

Popis výsledku v původním jazyce

The solution of quasistationary heat-conduction problems with moving heat sources on the surface of a body is a demanding task and still a topic of ongoing research. The authors have shown in several contributions that an exact analytical solution existsfor a constant velocity of the heat source and constant thermal properties of the body. Since also convection at the surface can be treated properly, cooling and quenching problems can be solved, accordingly. The main characteristic of the governing equation is that the partial derivative of the temperature with respect to time must be replaced by the convective term being the velocity of the heat source times the gradient of the temperature. In this contribution it is shown that the quasistationary problem can be transformed into a stationary one, if a modified heat-conduction coefficient is introduced. The application of this concept and its limits are demonstrated in comparison with existing analytical solutions. For this purpose a
