“…In particular, the light-scattering photon correlation spectroscopy (PCS) data of Will et al 47 provide thermal diffusivity data that were converted to thermal conductivity with q and C p calculated from the EOS. 39 This conversion process introduces additional uncertainty in the critical region, where the uncertainty in the calculated C p increases.

This paper contains new, representative equations for the thermal conductivity of toluene. The equations are based in part upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory whenever possible. Although there are a sufficiently large number of data at normal temperatures, data at very low and very high temperatures as well as near the critical region are scarce. In the case of the dilute-gas thermal conductivity, a theoretically based correlation was adopted in order to extend the temperature range of the experimental data. Moreover, in the critical region, the experimentally observed enhancement of the thermal conductivity is well represented by theoretically based equations containing just one adjustable parameter. The correlations are applicable for the temperature range from the triple point to 1000 K and pressures up to 1000 MPa. The overall uncertainty (considered to be estimates of a combined expanded uncertainty with a coverage factor of two) of the proposed correlation is estimated, for pressures less than 700 MPa and temperatures less than 550 K, to be less than 3% for the liquid, while for the region 550 K ≤ T ≤ 700 K the uncertainty is estimated to be 4%. For the region T > 700 K and 500 MPa ≤ p ≤ 1000 MPa, the equations can safely be used with an uncertainty of the order of 10%. Finally, the uncertainty along the saturation line is estimated to be 2% with a coverage factor of two.

“…Thermistor-based techniques are widely used for measurement of temperature, velocity and thermal properties of liquids, powders and biomaterials [1][2][3][4][5][6][7][8][9][10][11]. The characteristics of the negative temperature coefficient type thermistor, large output, high temperature sensitivity and usage both as heater and temperature sensor, make it adaptable to various measurement purposes.…”

“…With small scale, the miniature thermistor bead can be used as a 'point' heater and temperature sensor. Compared with other heat transfer models [4,5,[7][8][9][10], the 'point' assumption makes one not consider the complex structure of the thermistor, which makes the measurement convenient for application [6,11]. 3 Author to whom any correspondence should be addressed.…”

Experimental data of temperature versus time obtained by dual-thermistor heat pulse equipment can be analysed by two approaches to find the thermal diffusivity and the thermal conductivity. One, referred to as the peak point approach, is based on accurate identification of the peak point in the temperature versus time measurement. The other is a nonlinear fit approach by comparing the theoretical model with the experimental data. A sensitivity analysis is performed to define an optimal measurement time interval with a desired uncertainty limit for the nonlinear data fit. The experimental design can also be optimized from the sensitivity analysis. A comparison of the two approaches is presented according to the results of data processing.
