Separation of Nanoparticles from Nanoparticle Enhanced Phase Change Material

Keywords: , , ,

The phase change materials(PCM) have been used to store energy as a latent heat of fusion. Paraffin oils are proved to be the best suitable material as a PCM, however its heat capacity is lower which is enhanced by using nanoparticles. In our work dodecane (paraffin) is used as a PCM and Copper oxide(CuO) nanoparticles have been used to improve the thermal conductivity. This mixture is known as nano-enhanced phase change material(NEPCM). The objective of our work is to separate the nanoparticles before disposing off used NEPCM after its lifecycle. This is mainly due to the potential health hazard nanoparticles possess for all living organisms. In this work we will report the different methods which we have tried and worked successfully. This project deals with a very important and often less discussed aspect of nano-fluids/nano-colloids.
