ASME 2012 Third International Conference on Micro/Nanoscale Heat and Mass Transfer, 2012
The growing demand for microelectronic systems to be smaller and faster has increased the energy released by these devices in the form of heat. Microelectronic systems such as laptop computers and hand held devices are not exempted from these demands. The primary traditional technologies currently used to remove heat generated in these devices are fins

Solidification of nano-enhanced phase change material (NEPCM) in a wavy cavity
Heat and Mass Transfer, 2012The 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.
