O. Delgado-vasallo et E. Marin, The application of the photoacoustic technique to the measurement of the thermal effusivity of liquids, J PHYS D, 32(5), 1999, pp. 593-597
We describe the application of the photoacoustic technique to the thermal c
haracterization of liquids. An experimental method which allows the experim
ental determination of the thermal effusivity in transparent as well as in
light absorbing samples is proposed. The method is tested by measurements i
n water, ethanol, diffusion-pump oil, glycerol and petroleum. Our results a
gree quite well with the literature reported values for these samples.
