In the case of solidification in cylindrical radial heat flow, despite the technological importance, few studies have been produced in this area.

Thus, it was reasonable to assume that the axial heat losses were small compared to the magnitude of the radial heat flow. However, even though the resulting [Q.sub.leak,in] was fairly small it was accounted for during the calibration procedures to eliminate a systematic error on the actual thermal conductivity of the sand inside the Aluminum pipe.
