Thermal diffusivity effect in opto-thermal skin measurements

Measurement Thermal Conductivity and Thermal Diffusivity of Chromium Nanofluids

In this study, nanofluids of Chromium (Cr) in water, Ethylene Glycol and Ethanol have been prepared using single step method. The thermal conductivity and diffusivity of these nanofluids were measured via hot wire-photothermal deflection technique. Based on finite difference method (FDM) temperature distribution and photothermal deflection caused by the hot wire inside nanofluids was obtained. ...

Investigation of Variability in Skin Tissue Intrinsic Thermal Conductivity Measurements

The Thermal Diffusion Probe 200 (TDP200) is a thermal properties characterization device that is capable of measuring the thermal conductivity of phantom materials with less than 0.2% variability. However, this device gives 1.5% to 2% variability in thermal conductivity values when the medium being measured is human skin tissue. Six different sources of variability have been identified that mig...
