Fig. 3: Thermal conductivity of liquids at different temperatures.
From: Accurate and rapid measurement of fluid thermal conductivity
a Temperature control setup with feedback from a central thermocouple, connected to heaters that turn off upon reaching the set-point. b Thermocouple response to a set-point increase from 23 °C to 53 °C, showing a 3 min stabilization time, compared to a 1 min simulation assuming perfect heat transfer to the device and ignoring the controller effects. Measured thermal conductivity of ethanol (c), ethylene glycol (d), and ethyl laurate (e), respectively, from 10–67 °C, with quadratic fits (dashed lines) matching literature data (solid lines)35. Markers indicate the mean of three measurements; error bars denote the standard deviation. Source data are provided as a Source Data file.
