Simulación y procesado de aleaciones de aluminio mediante estirado en canal angular constante (ECAD)
En este trabajo se estudia el proceso denominado ECAD (Equal Channel Angular Drawing) que consiste en hacer atravesar un material a través de una matriz de sección transversal constante, que presenta un ángulo comprendido, ... -
Strain mapping and nanocrystallite size determination by neutron diffraction in an aluminum alloy (AA5083) severely plastically deformed through equal channel angular pressing
Six specimens of an aluminum alloy (AA-5083) extruded by Equal Channel Angular Pressing following two different routes plus a blank sample were examined with a neutron radiation of 1.5448 ˚ A. Macrostrain maps from the ... -
Study of a complete thermoelectric generator behavior including water-to-ambient heat dissipation on the cold side
The reduction of the thermal resistances of the heat exchangers of a thermoelectric generation system (TEG), leads to a significant increase in the TEG efficiency. For the cold side of a thermoelectric module (TEM), a wide ... -
Study of corrosion in a biomass boiler
Biomass plants, apart from producing energy, help to reduce CO2(g) emissions. One of the biggest problems for their development is superheater corrosion due to fuel corrosivity, especially of the straw. This limits both ... -
Study of thermoelectric systems applied to electric power generation
A computational model has been developed in order to simulate the thermal and electric behaviour of the thermoelectric generators. This model solves the non linear system of equations of the thermoelectric and heat transfer ... -
Surface roughness analysis on the dry turning of an Al-Cu alloy
Nowadays, surface finish has become an important indicator of quality and precision in manufacturing processes and it is considered one of the most important parameter in Industry. In this present study, the influence of ... -
Symbolic multibody methods for real-time simulation of railway vehicles
In this work, recently developed state-of-the-art symbolic multibody methods are tested to accurately model a complex railway vehicle. The model is generated using a symbolic implementation of the principle of virtual ... -
A theoretical model of the endothelial cell morphology due to different waveforms
Endothelial cells are key units in the regulatory biological process of blood vessels. They represent an interface to transmit variations on the fluid dynamic changes. They are able to adapt its cytoskeleton, by means of ... -
Thermoelectric generators for waste heat harvesting: a computational and experimental approach
Waste heat generation has a widespread presence into daily applications, however, due to the low-temperature grade which presents, its exploitation with the most common technologies is complicated. Thermoelectricity ... -
Thermoelectric self-cooling for power electronics: increasing the cooling power
Thermoelectric self-cooling was firstly conceived to increase, without electricity consumption, the cooling power of passive cooling systems. This paper studies the combination of heat pipe exchangers and thermoelectric ... -
Thermoelectric-driven autonomous sensors for a biomass power plant
This work presents the design and development of a thermoelectric generator intended to harness waste heat in a biomass power plant, and generate electric power to operate sensors and the required electronics for wireless ... -
Zero-power-consumption thermoelectric system to prevent overheating in solar collectors
Highly promoted by the European Union Climate and Energy Package for 2020, solar collectors stand out as the most promising alternative to meet water heating demands. One of the most limiting problems in these systems ...
