Second law analysis and heat transfer in a cross-flow heat exchanger with a new winglet-type vortex generator
(Elsevier Ltd, 2010)
In this paper a second law analysis of a cross-flow heat exchanger (HX) is studied in the presence of a balance between the entropy generation due to heat transfer and fluid friction. The entropy generation in a cross-flow ...
Exergy transfer in a porous rectangular channel
(Elsevier Ltd, 2009)
Present paper is performed to investigate the heat and exergy transfer characteristics of forced convection flow through a horizontal rectangular channel where open-cell metal foams of different pore densities such as 10, ...
