Temperature dependence of thermal conductivity of biological tissues

Physiological Measurement, 2003
In this paper, we present our experimental results on the determination of the thermal conductivity of biological tissues using a transient technique based on the principles of the cylindrical hot-wire method. A novel, 1.45 mm diameter, 50 mm long hot-wire probe was deployed. Initial measurements were made on sponge, gelatin and Styrofoam insulation to

Temperature Dependence of Thermal Conductivity of Nanofluids

Chinese Physics Letters, 2008
Mechanism of thermal conductivity of nanofluids is analysed and calculated, including Brownian motion effects, particle agglomeration and viscosity, together influenced by temperature. The results show that only Brownian motion as reported is not enough to describe the temperature dependence of the thermal conductivity of nanofluids.

The Temperature Dependence of the Thermal Conductivity of Air

Australian Journal of Scientific Research Series A: Physical Sciences, 1951
The thermal conductivity of air is determined in absolute measure between -183 and 218 °C. by the " thick-wire " variant of the " hot-wire " method. The apparatus consists of a platinum wire 11 6 cm. long and 1.5 mm. in diameter mounted in a 90 per cent. Pt 10 per cent. Ir tube of 7 mm. internal diameter.
