Numerical analysis of a modified evacuated tubes solar collector
The need for renewable energy sources, facing the consequences of Climate Change, results in growing investment for solar collectors’ use. Research in this field has accompanied this expansion and evacuated tube solar ...
Modeling flow and heat transfer in tubes using a fast CFD formulation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2001)
Rheology and fluid dynamics properties of sugarcane juice
The sugarcane juice is a relatively low-cost agricultural resource, abundant in South Asia, Central America and Brazil, with vast applications in producing ethanol biofuel. In that way, a good knowledge of the rheological ...
Simulação numérica de trocadores de calor multitubulares equipados com fitas helicoidais externamente aos tubos
Classical shell-and-tube heat exchangers are usually equipped with segmental baffles. These baffles serve two basic functions: (a) they provide tube supports, thereby preventing or reducing mechanical problems, such as ...
Conventional and modified fluidized bed: Comparison of the fluid dynamics and application in particle granulation
(Elsevier Science SaLausanneSuíça, 2009)
Demulsification of water/sunflower oil emulsions by a tangential filtration process using chemically impregnated ceramic tubes
(Elsevier B.V., 2007-02-15)
A tangential filtration process was implemented in this study using porous ceramic tubes made of alpha-alumina produced by the slip-casting technique. These tubes were sintered at 1450 degrees C and characterized by mercury ...
Simulation of the behavior of a dense SiC particle suspension as an energy transporting vector using computational fluid dynamics (CFD)
(Institution of Chemical Engineers, 2016-02)
In the search for greater efficiency and storage capacity improvements in solar energy concentration plants, a new concept for fluid transfer was proposed. This concept consists of a dense suspension of SiC particles (dp ...
On the radial expansion of tubular structures in a quark-gluon plasma
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We study the radial expansion of cylindrical tubes in a hot QGP. These tubes are treated as perturbations in the energy density of the system which is formed in heavy ion collisions at RHIC and LHC. We start from the ...
