On PCM Enhanced Heat Transfer Technique

Audio Watermarking Based on PCM Technique

Digital instruments come to be used in Desk Top Music (DTM), live performance, etc. These performances are recorded as digital contents, and circulated actively through network and electronic media. Digital Water mark technology paid much attention to solve the problem of illegal distribution & duplication when the digital contents are spread over electronic media. In this paper, we focus on a ...

Nanowires for enhanced boiling heat transfer.

Boiling is a common mechanism for liquid-vapor phase transition and is widely exploited in power generation and refrigeration devices and systems. The efficacy of boiling heat transfer is characterized by two parameters: (a) heat transfer coefficient (HTC) or the thermal conductance; (b) the critical heat flux (CHF) limit that demarcates the transition from high HTC to very low HTC. While incre...

Numerical Simulation of Heat and Moisture Transfer in Porous Walls with Microencapsulated PCM

Heat Transfer Modelling within Graphite/pcm Composite Materials for High Temperature Energy Storage

Moderately compressed exfoliated graphite (CEG) leads to highly porous graphite “foams” or matrices which have numerous actual and potential applications. The graphite/salt composite materials considered here for high temperature energy storage applications, as due to its superior heat conduction and thermal storage characteristics, are manufactured by uniaxial compression of a mixture of salt ...

A model for enhanced heat transfer in an enclosure using Nano-aerosols

In this study, the behavior of nanoparticles using a numerical model is discussed. For this study a model for the expansion in free convection heat transfer and mix in a rectangular container with dimensions of 1 × 4 cm using Nano-aerosols in the air is going when copper nanoparticles, use and by changing the temperature difference between hot and cold wall, we will examine its impact on the ra...
