Criteria for mixed grids in computational fluid dynamics
(Elsevier B.V., 2006-11-06)
The finite volume method is used as a numerical method for solving the fluid flow equations. This method is appropriate to employ under structured and unstructured meshes. Mixed grids, combining both types of grids, are ...
Structural dynamic analysis of vertical bars of turbine protection trashracks of hydroelectric plant
(2016-01-01)
Trashracks of hydroelectric plants are very important equipment because they are responsible for protection of hydraulic turbines against impact of floating bodies. These structures are basically constituted by horizontal ...
Propriedades dinâmicas de fluidos por simulação computacional: métodos híbridos atomístico-contínuo
(Sociedade Brasileira de Química, 2010)
Computational methods for the calculation of dynamical properties of fluids might consider the system as a continuum or as an assembly of molecules. Molecular dynamics (MD) simulation includes molecular resolution, whereas ...
Optimal Design of a Corrugated-Wall Photocatalytic Reactor Using Efficiencies in Series and Computational Fluid Dynamics (CFD) Modeling
(American Chemical Society, 2013-04)
The optimization of a corrugated wall photocatalytic reactor for air treatment was addressed using the concept of efficiencies in series. A new concept has been introduced: the inner incidence efficiency, associated with ...
Coupling Concept of two Parallel Research Codesfor Two and Three Dimensional Fluid Structure Interaction Analysis
(World Academy of Science, Engineering and Technology, 2014-06)
This paper discuss a coupling strategy of two different software packages to provide fluid structure interaction (FSI) analysis. The basic idea is to combine the advantages of the two codes to create a powerful FSI solver ...
DEVELOPMENT OF STATIC MIXERS FOR MISCIBLE FLUIDS IN LAMINAR FLOW WITH THE USE OF COMPUTATIONAL FLUID DYNAMICS (CFD)
(WILEY-BLACKWELL, 2011)
Static mixers with improved performance were developed from CFD simulations in a stepwise approach. The relevant geometric features of simple mixer designs and the corresponding mixing mechanisms-laminar shear, elongational ...
Análise numérico-experimental da agitação de calda em reservatórios de pulverizadores agrícolas
(2015-01-01)
This paper presents a numerical and experimental study of spray fluid performance with stirring in tanks of agricultural sprayers. The pesticide spray should be stirred properly to ensure spraying homogeneity throughout ...
