The comparative analysis on using the NEPCM materials and nanofluids for microchannel cooling solutions

International Communications in Heat and Mass Transfer, 2016
Abstract This paper presents numerical analysis on microchannel laminar heat transfer and fluid flow of nanoencapsulated phase change materials (NEPCM) - water slurry as coolant, with two different melting ranges, 5 °C and 20 °C. In this study n-Octadecane for NEPCM and water is used as base fluid.

Solidification of nano-enhanced phase change material (NEPCM) in a wavy cavity

Heat and Mass Transfer, 2012
The effects of surface waviness (λ = 0, 0.125, 0.25, 0.5) and nanoparticle dispersion (ϕ = 0, 0.05, 0.1) on solidification of Cu-water nanofluid inside a vertical enclosure are investigated numerically for different Grashof number (Gr = 105, 106, 107). An enthalpy porosity technique is used to trace the solid and liquid interface.
