Abstract EN
Photoacoustic (PA) sensor was designed and developed to evaluate thermal effusivity of Fe3O4 nanofluid.
The PA sensor is based on open cell mode (OPC) to measure acoustic signals from low concentration of nanoparticulate suspensions in ethylene glycol (EG).
Spherical Fe3O4 nanoparticles (NPs) were obtained by chemical precipitation method in powder form.
The obtained NPs were stabilized by acetylacetone (acac) in EG.
Thermal conductivity estimation was carried out with the help of transient hot wire method.
The developed PA sensor was calibrated by measuring thermal effusivity of standard samples.
The acoustic signals of the PA experiments have been analyzed with a simple Rosencwaig-Gersho theoretical model.
