Measurement studies of thermal conductivity of water and coconut oil with nanoparticles dopant for thermal energy storage
2021
The increasing need for energy is still the main issue and had led to finding solutions in many research. Heat transfer fluid and phase change material (PCM) are feasible thermal energy storage materials. For these two types of materials, thermal conductivity is an important parameter to be determined. Measurement of thermal conductivity is highly dependent on chemical composition, physical structure, and also tools of measurement. Thermal conductivity measurements are generally carried out by giving heat to the materials but still paying attention to the resulted temperature and the time duration of measurement to avoid making convection which makes the results inaccurate. Therefore, in this experiment we have investigated thermal conductivity of water and coconut oil (co_oil) as heat transfer fluid using the Decagon devices KD2Pro thermal analyzer that uses the transient line heat source. The results of data analysis are compared with the direct data from the devices, and the obtained results for the thermal conductivity of water are compared with the data from references.
