Finally, the thermal resistivity per unit area of the wetsuit material was obtained with the product of the wetsuit sample's thermal resistance and the wetsuit area. The measurements, conducted until now by immersing the phantom in a free surface tank, show that both methods鈥攗nder stationary ...
Alternatively, in an electrical analogy (used frequently), the inverse of thermal conductivity (i.e., the thermal resistivity) is the material's propensity to impede the flow of heat. More formally, thermal conductivity can be expressed in terms of Fourier's law of steady-state heat conduction...

The reciprocal of thermal conductivity is thermal resistivity, usually measured in kelvin-meters per watt (K·m·W−1). When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermal resistance, can be described. Unfortunately, there are differing ...
The effect of soil density on TRDC was analyzed using four density parameters: (a) maximum dry unit weight (?dmax), (b) minimum void ratio (emin), (c) maximum void ratio (emax), and (d) coefficient of uniformity (Cu). Soil thermal resistivity 展开 ...
