Fig. 14. The temperature (T) distribution along the axis of the sensing needle in a parallelepiped (length a = width b = 5 cm for lines, and a = b = 10 cm for circle symbol C) for (a) adiabatic boundary conditions (ABC) and probe length of 3 cm, and (b) zero surface temperature (ZST) boundary condition and probe length/sample height ratios of 0.1, 0.2, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1 at time t = 60 s. Needle spacing was fixed (r = 6 mm). Arrows indicate the midpoint position of the sensing needle, which is parallel along the z axis.
