Exergy analysis of the steam-injected gas turbine
In this paper, the effect of steam injection in the combustion chamber on the exergy efficiency of a gas turbine was investigated. Cycle exergy efficiency, net power output and exergy destruction have been calculated for different mass flow rates and temperature of the injected steam. The range of variation of the mass flow rate was between 0 and 5.24% of the design air flow rate, and the ...

A Finite Element Method analysis and optimisation of a polymer electrolyte membrane fuel cell with interdigitated flow field design
Interdigitated polymer electrolyte fuel cells are particularly attractive due to the enhanced transport rates and benefits with respect to electrode flooding. A 2D isothermal model is used to simulate the outlining processes that occur at the elemental fuel cell level. A Finite Element Method analysis is conducted to simulate the flow and current density fields for different gas channel ...

Evaluation of power input efficiency for China's typical cities based on the DEA and SFA models
China is entering a rapid developmental stage of urbanisation characterised by tremendous economic development. However, many prominent problems have existed for a long time. Among these, problems on power efficiency should be addressed. The extended models of data envelopment analysis (DEA) and stochastic frontier analysis (SFA) were used to analyse city input-output efficiency including ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
