Results in brief
Using Phase Change Materials for the Base Suspension in the Creation of NanoFluids
Phase Change Materials (PCMs) provide an innovative way to handle the increased need for heat transfer and thermal efficiency. PCMs can constitute a wide variety of materials, but are required to possess large latent heats. Organic compounds including hydrocarbons are ideally suited for use as PCMs, but the thermal property data is quite scarce and what is available is only very few data with high standard deviations considering the experimental set-ups used. The research is important to society because there is a significant need for more research and development in the field of thermal properties of PCMs in order to improve heat transfer capabilities in any thermal processes and/or for thermal energy storage. Furthermore, it is possible that the addition of nanoparticles to certain organic compounds can further enhance the PCMs’ heat transfer properties. Therefore, using an organic compound as the base suspension for the creation of a nanofluid should produce a working fluid with thermal transport properties far greater than anything in use today. Then, if successful, this action will provide a means of thermal transport (cooling or storage) beyond today’s current state-of-the-art. The first work package of the action is to determine the thermal properties of possible PCMs for different base suspension (hydrocarbons) materials using the Transient Hot-Wire (THW) Method. The second work package will use the PCMs from the first phase as a base suspension to create different nanofluids, which will then be tested in the same manner as the base fluids in the first phase. Once all of the experiments have been concluded the data and results will be compared to the base fluids. The nanofluids are expected to produce an order of magnitude higher thermal conductivity than the base fluids alone. In the PCMNano project, the developed and tested nanofluids using different types of nano-particles, including some commercial nanofluids, do not show such expected enhancement of the thermal conductivity.

Project objective
Nano-fluids (fluid bases with a nano-particle suspension) and Phase Change Materials (PCM) provide innovative ways to handle the increased need for heat transfer and thermal efficiency. But information regarding the thermal properties (thermal conductivity, thermal diffusivity, enthalpy of transformation, enthalpy of fusion/melting, enthalpy of vaporization, specific heat, melting temperature, and crystallization temperature) of nano-fluids and PCMs is limited and antiquated. Therefore, is the purpose of this action to determine the thermal properties of a number of PCMs to then use as the base fluid for a number of nano-fluids. This will be done by measuring n-alkanes in both the solid and liquid phases using the transient hot wire and the differential scanning calorimetry (DSC) techniques. When possible, the obtained results will be compared with the scarcely available literature data. Lastly, the creation of a thermal properties prediction model for the nano-fluids will be attempted.
