(thermodynamics)
Flow of heat between two coaxial cylinders maintained at different temperatures; used to measure thermal conductivities of gases.

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.
The boundary conditions at the borehole wall are that the temperature and the radial heat flow are continuous:
