Melting of Nanoprticle-Enhanced Phase Change Material inside Shell and Tube Heat Exchanger

الملخص EN

This paper presents a numerical study of melting of Nanoprticle-Enhanced phase change material (NEPCM) inside a shell and tube heat exchanger using RT50 and copper particles as base material and nanoparticle, respectively.

In this study, the effects of nanoparticles dispersion (ϕ=0, 0.03, and 0.05) on melting time, liquid fraction, and penetration length are investigated.

The results show that the melting time decreases to 14.6% and the penetration length increases to 146% with increasing volume fraction of nanoparticle up to ϕ=0.05.
