Measurement of refractive index of PF-5060 Original Research Article

For optical studies of boiling heat transfer process, it is essential that the refractive index and its dependence on temperature for the test liquid be known. In this work a simple set-up was built to measure the refractive index of Fluorinert Liquid PF-5060 with temperature compensation and temperature control. The pinhole laser light beam was used for determining the refraction angle. The refractive index data obtained in the temperature range 0–60°C is found to correlate linearly with temperature.
