| Sumario: | The present thesis deals with the synthesis and characterisation of nanofluids including phase change materials as the nanoparticles. The main aim of the work is to develop new materials that suppose an improvement on the heat transfer properties and heat storage capacity with respect to the current available technologies. Several nanofluids based on thermal oils and molten salts have been synthetised and characterised in order to study the influence of the addition of nanoencapsulated phase change materials in their thermal properties such as thermal conductivity, heat thernal capacity, specific heat and heat storage capacity. Additionally, the use of Atomic Layer Deposition to synthetise material layers of a few nanometers as encapsulation and their influence on the nanofluids characteristics have been studied. |
