Additive manufacturing is growing rapidly in the automotive, medical, and aerospace industries as an option for of products. However, there a continuous growth amount waste generated by 3D filaments, thus, reuse practice becomes important, since it brings environmental economic gains. The present research evaluated mechanical, thermal, thermomechanical rheological properties PLA/PLAr blends containing post-consumption filament. were prepared co-rotational twin screw extruder and,...
Este artigo apresenta uma análise de eficiência energética e exergética um sistema refrigeração água gelada grande porte, chiller, integrado a central projetada para suprir carga térmica necessária do ar shopping localizado na capital estado da Paraíba, Brasil. O chiller estudado utiliza compressor tipo parafuso, que opera com motor elétrico aumentar pressão em fase ciclo termodinâmico, resultando consumo significativo energia, especialmente operações contínuas sob elevada. estudo se...
The aim of this research is to study the pollutant emissions commercial diesel engine, operating with B5 (commercial diesel), B70, B80, B90 and natural gas. fuel used in engine consists a mixture 15% biodiesel (liquid fuel) 85% Experiments were made using 40, 60 80 kW load. was instrumented obtain temperature, air, gas (plus biodiesel) flow rates, air pressure at entrance lubricant oil concentration exhaust gases during each experimental test. It verified that emission NO x , CO 2 had...
