Photoacoustic measurements of transparent liquid samples: thermal effusivity

Abstract

In this paper we describe the use of the open photoacoustic cell (OPC) to obtain the thermal effusivity of transparent liquid samples. The samples used to demonstrate the usefulness of the OPC configuration were distilled water, diffusion pump fluid oil, amaranth seed oil, car oil, glycerol and some solvent liquids, such as trichloroethylene, isopropanol, white gasoline and ethanol.
