Temperature and penetration depth prediction for a three-dimensional field below a moving heat source (Q1310661)

Predictions for both penetration depth of a specific isotherm and for peak temperatures achieved during processing of brick-type workpieces are inferred. A rectangular heated area is thereby travelled at constant speed across the top surface of the workpiece. The model accounts for the finite cross-track extents of the workpiece as well as for a realistic heat transfer towards an underlying table. The model is strictly valid for conduction-dominated processes. New results are obtained for cases where, due to geometry of workpiece and heated area, truly three- dimensional heat flow situations are present.
