Abstract: This project work deals with the fabrication of steady-state parallel-plate thermal conductivity (PPTC) apparatus to determine the effective thermal conductivity of base fluid and nanofluids and to show the enhancement in the effective thermal conductivity of nanofluids. A nanofluid is a fluid containing nanometer-sized particles called nanoparticles. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. In this project water is taken as base fluid and nanoparticles of silver and graphene quantum dots are used to prepare nanofluids. The steady state PPTC apparatus consists of two square copper plate kept at a distance of 8mm in which the test fluid specimen is filled and the top plate is imbedded with a heater assembly. This creates a temperature difference which is measured by calibrated LM 35 temperature sensor imbedded in the parallel plates. This temperature difference is then used, along with the heating power, to calculate the thermal conductivity of the test fluid specimen using fourier’s law of heat conduction.
