Studies on directional and rapid solidification of Al‐B‐Cu composites
(2007)
The present work studies the effect of directional and rapid solidification on the
distributions of borides reinforcements and mechanical properties of Al-B-Cu
composites. To analyze the influence of these two manufacturing ...
Towards the development of an automated, portable enterococcus faecalis biosensor for recreational waters
(2018)
The quality of recreational waters is of great importance to the public. Enterococcus faecalis is one of the main indicators of recreational water quality. The standardized technology for quantifying bacterial concentrations ...
Micro damage initiation and progression for isotropic and composites structure using strain invariant failure theory
(2015-09)
In this work, we focus our attention on initiation and progressive damage of isotropic
and composite structures using Strain Invariant Failure Theory (SIFT) at the micro-level.
The stress-based tools are very popular to ...
Transport phenomena in crossflow jets subject to very strong favorable pressure gradient
(2020-12-10)
Incompressible jets transversely issuing into a spatially-developing turbulent boundary
layer is one of the most challenging types of three dimensional flows not only due to its
fluid-dynamic complexity but also due to ...
Study of volume variations in alpha stirling engine design via a discrete control volume approach
(2014)
New demand for cleaner and low cost energy production are factors that have increased interest in the Stirling engine as a plausible alternative to internal combustion engines. The Stirling engine is based on the principles ...
Temperature field determination in slabs, circular plates and spheres with saw tooth heat generating sources
(2010)
The Green's functions integral technique is used to determine the conduction heat transfer temperature field in flat plates, circular plates, and solid spheres with saw tooth heat generating sources. In all cases the ...
On the selection of commercially available Sn-Ag-Cu Pb-free balls components over re-balling the components with Sn37Pb balls to comply with the restriction of hazardous substances directive in the aerospace industry
(2009)
A modeling approach based on physics of failure is presented that quantifies the interactions between different thermal cycles applied to Ball Grid Arrays (BGA). The approach is formulated at the microscale, incorporating ...
Numerical simulation of the structure of time dependent homogeneous, isotropic turbulence
(2009)
We consider physical situation of homogeneous, isotropic decaying turbulence in an
incompressible fluid for computational study. It is well established that laminar and
turbulent flows of Newtonian fluids are governed ...
Influencia de los parámetros termomecánicos en el efecto de doble memoria de forma del nitinol
(2009)
The two way shape memory effect (TWSME), is described as a reversible change in the form of a shape memory alloy (SMA). The Nitinol alloy is one of the materials that reflect this phenomenon best. This investigation seeks ...
Development of a magnetocaloric pump for applications in heat pipes
(2005)
A device that can pump a fluid with no moving mechanical parts represents a very encouraging alternative since such device would be practically maintenance free. A magnetocaloric pump achieves this purpose by providing a ...
