Investigation on performance of a compression-ignition engine with pressure-wave supercharger

The use of grey-based methods in multi-criteria decision analysis for the evaluation of sustainable energy systems: A review

“…As other studies have noted, multi-criteria optimization analysis methods have gained in popularity beyond 1990s [9]. Selecting fuels [42,45,48,54,58], optimize operation conditions [44,46,47,53,60], environmental impact assessment, in terms of emissions [49,50,55,61] are the main applications identified in the recent literature. Moreover, it is well recognized that the GRA method in several research fields other than energy to deal with project selection, prediction analysis, performance assessment or factor effect evaluation [30].…”

“…Exergy efficiency may be understood in terms of work. Although exergetic analysis was initially exclusively implemented in the field of industrial ecology, in recent years it has been used in other fields, such as thermal engines [60].…”

Contribución a la Mejora del Margen de Bombeo en Compresores Centrífugos de Sobrealimentación

“…El cilindro distribuidor está acoplado mecánicamente al cigüeñal, pero solo consume potencia para su arrastre. En consecuencia, se tiene una respuesta de sobrealimentación inmediata dando lugar a un gran par a bajos regímenes de motor [54,73]. Sin embargo, tiene como inconvenientes ser un sistema caro, voluminoso y muy ruidoso, además de problemas de fatiga térmica en el cilindro distribuidor por estar sometido a fuertes ciclos alternos de temperatura.…”

Multi-Objective Optimization Design of a Novel Integral Squeeze Film Bearing Damper

“…The application of the GRA algorithm is to select the optimized points in the Pareto frontier as a reference sequence for normalizing the orthogonal experimental data [24][25][26]:…”
