Fig. 4. Calculated long-time temperature (T) curves (a) at the thermocouple location for a pulsed infinite line source (dash-dot line), a pulsed infinite cylindrical source (long dash line), a pulsed finite line source (short dash line), and a pulsed finite line source in a parallelepiped (5 by 5 by 5 cm3) with zero surface temperature (ZST, solid line) and adiabatic boundary condition (ABC, dotted line); and (b) for a pulsed finite line source in the same parallelepiped.
