Paper Abstract

There is commonly assumed in photoacoustic studies that the answer to sinusoidal excitation to the system is sinusoidal. In the presented contribution, using so-called an open-type photoacoustic cell, the effect of thermal signal shape was evaluated. In the studies, water was used as a reference medium of well-determined thermal diffusivity. Fresh and degraded oils were selected as studied liquids. The values of (alpha) obtained for fresh oils and degraded ones are in agreement with the table reference data reported for similar kinds of oils.
