Trends in crystalline silicon photovoltaic improvements demonstrate that some of the key factors have contributed to reaching efficiency values up 23 % are introduction passivated emitter and rear cell structure with local contacts low-cost large-volume fabrication; reduction width front metallization fingers, from about 100 microm less than 30 micro m large volume production, re-emergence mono...

Liquid-cooled hot plates require effective thermal management which can be accomplished by implementing appropriate cooling architectures. This investigation is about high heat-generating systems and reports the performance of heated with various flow configurations: Serpentine flow, parallel tubes two tree-shape systems. Single double objectives size constraint are studied to obtain best desig...

Industrial, residential and commercial noise levels are to be maintained for acoustic comfort living conditions. Sound annoyance is a sensation of discontentment linked with any driving force from machines or circumstance. It certain that, can harm human hearing capacity brain neuron cells. Novelty this study was the design window air conditioner modified heat exchanger coils phase change mater...

Several stiffened plates arrangements subjected to bending were configured applying the Constructal Design Method (CDM) and solved by Finite Element (FEM), aiming through Exhaustive Search (ES) technique analyze influence of transverse I-Shaped or T-Shaped stiffeners in mechanical behavior. Considering a non-stiffened plate as reference maintaining total steel volume constant, portion was deduc...

A numerical study was performed in the present work about an Overtopping Device Wave Energy Converter (OTD-WEC) with one and two ramps incorporated a real breakwater. The Constructal Design method applied to evaluate effects on average dimensionless overtopping flow of degrees freedom device ramps. In addition, comparison carried out among different geometry configurations OTD-WEC determine whi...
