Experimental Measurements on the Thermal Conductivity of Glycerol-Based Nanofluids with Different Thermal Contrasts

Table 3

Values of the thermal conductivity (in W·m−¹·K−¹), measured for three different glycerol-based nanofluids, as a function of the volume fraction φ, at room temperature. For each nanofluid, the correlation coefficient was greater than 0.99.
