A dynamic model of a centrifugal compressor capable of system simulation in the virtual test bed (VTB) computational environment is presented. The model is based on first principles, i.e. the dynamic performance including the losses is determined from the compressor geometry and not from the experimentally determined characteristic performance curves. In this study, the compressor losses, such ...

This study investigates how high levels of exhaust gas recirculation (EGR) combined with certain fuel injection strategies and energy recovery systems affect diesel engine emissions and fuel economy. The key test apparatus was a John Deere 4.5L diesel engine which was modeled using the computer-based engine simulation tool GT-Power. The conclusion was made that utilization of high EGR levels (3...

Concentrating solar power (CSP) is a high-potential renewable energy source that can leverage various thermal applications. CSP plant development has therefore become global trend. However, the designing of for given resource condition and financial situation still work in progress. This study aims to develop mathematical model analyze levelized cost electricity (LCOE) Thermal Energy Storage (T...

Supercritical carbon dioxide (S-CO2) has the advantages of amphoteric liquid and gas, which possesses many unique characteristics, such as good compressibility, high density, solubility, fluidity low viscosity. The Brayton cycle with S-CO2 is considered to have promising applications, especially for power conversion industries. However, corrosion degradation structural materials hinder developm...
