Abstract
This paper analyses the passive augmentation of convective heat transfer administering the nanoporous layers fabricated by electrochemical anodization and spray pyrolysis. Nanoporous structures fabricated in electrochemical anodization have pore size varying from 40 to 120 nm, and the pore size procured in spray pyrolysis fluctuates from 60 to 100 nm. Convective energy transfer greatly banks on surface attributes. These nanoporous structures aid in hindering the dynamic flow of fluid and the turbulence is achieved more expeditiously. The proliferation of the convective heat transfer obtained with electrochemically anodized nanoporous surface is 131% higher than the polished bare metals with surface roughness 0.2 μm. In case of spray pyrolysis the maximum proliferation is 120%. Disparate disciplines of nanoporous fabrication are perused for asserting a productive process. This paper also analyses the control parameters in the nanoporous fabrication process.
