EXPERIMENTAL INVESTIGATION ON THE CHARACTERISTICS OF NANOFLUIDS PCMS FOR COOL STORAGE

摘要：

Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids required in thermal energy storage applications. To overcome this limitation, a new sorts of heat transfer fluids is being developed by suspending 0.167, 0.283,0.565 and 1.13 vol.％ of TiO2 nanoparticles in saturated BaCl2 aqueous solution. The resulting nanofluids possess remarkably high thermal conductivities compared to the liquids without dispersed nanoparticles. Cool storage experiment made in a small apparatus also verified the excellent thermal properties of nanofluids. The cool storage rate and cool storage capacity increase remarkably than that of BaCl2 aqueous solution without added nanoparticles.
