A PHOTOACOUSTIC AND ULTRASONIC STUDY ON JATROPHA OIL
Using the photoacoustic technique, the thermal diffusivity of the dimethoxymethane + jatropha liquid mixture and pure jatropha oil is measured at room temperature. The result is correlated with the result of ultrasonic measurements. Keywords: Photoacoustics, thermal properties, jatropha oil. 1)Sri Meenakshi Government College for Women, Madurai, 625009, India; email: bamavihas@rediffmail.com; 2)School of Physics, Madurai Kamaraj University, Madurai, 625009, India.
