Thermal Conductivity of a Frozen Hubbard Loamy Sand
The heat transfer characteristics of a naturally occurring field soil were examined. A transient-state, cylindrical thermal probe was built. Tests were conducted on a fine Ottawa sand under both dry and saturated conditions to compare the probe response to results reported previously. Thermal conductivities of a naturally occurring, frozen, Hubbard loamy sand were determined at five soil moisture contents at temperatures of -15.5 and -2.5C. Results show a range in measured conductivity values from a low of .437 watts/mC at a moisture content of .82% by weight to a high of 1.74 watts/mC at 16.6% moisture content.
