Second law analysis of a gravity-driven liquid film flowing along an inclined plate subjected to constant wall temperature
( Inderscience Publishers , 2014 , Article)The second law analysis of a gravity-driven liquid having temperature-dependent viscosity and flowing along an inclined heated plate was studied. The computational fluid dynamics (CFD) package FLUENT was used to obtain the ... -
Second law analysis of compressible flow through a diffuser subjected to constant heat flux at wall
( Elsevier Ltd , 2010 , Article)Entropy generation is equivalent to destruction of available work (exergy). The useful energy is destroyed due to the intrinsic irreversibility associated within thermodynamic systems. Exergy analysis can be used as an ... -
Second law analysis of compressible flow through a diffuser subjected to constant wall temperature
( Inderscience , 2010 , Article)This study presents the investigation of entropy generation in compressible turbulent flow of air through a diffuser. Constant temperature boundary condition is applied at the wall. Two-dimensional solution of velocity and ... -
Selective adsorption of carbon dioxide, methane and nitrogen using resorcinol-formaldehyde-xerogel activated carbon
( Springer New York LLC , 2017 , Article)Resorcinol–formaldehyde xerogel was prepared, carbonized and activated in specific conditions to form resorcinol–formaldehyde activated carbon xerogel (RF-ACX) that was to produce microporous nanoparticles. RF-ACX was used ... -
