...Raub W. Smith The best assurance an owner has to maximize the performance of the entire combined cycle power plant is the perfect alignment of heat recovery steam generator (HRSG) performance guarantee metrics to this goal. Currently, HRSG equipment performance guarantees include steam generation...

...Seyfi Polat; Hamit Solmaz; Ahmet Uyumaz; Alper Calam; Emre Yılmaz; H. Serdar Yucesu In this study, the effects of negative valve overlap (NVO) on homogenous charge compression ignition (HCCI) combustion and engine performance were experimentally investigated. A four stroke, single cylinder, port...

...Dapeng Hu; Yiming Zhao; Teng Wu; Zhonghui Li; Yang Yu; Jingxian Wang The gas wave ejector (GWE) is an efficient gas wave equipment using pressure waves to realize energy exchange. In this paper, a theoretical analysis of the limitation of application range and the factors affecting the performance...

...Lijiang Wei; Anmin Wu; Jie Liu; Mingliang Zhong; Xuebai Wang For the two-stroke marine diesel engine, the action of exhaust valve has a significant impact on scavenging and combustion processes and ultimately affects the engine performances and emissions. In order to reduce nitrogen oxides (NO x...

... and smoke emissions; however, there is the engine derating as performance penalty in comparison to engines operating under PDM. The most influential parameters in DFM engines are the type and flow rate of inducted gaseous fuel, fuel–air equivalence ratio ( Φ global ), compression ratio (CR), and injection...

...L. Savadkouhi; S. A. Jazayeri; N. Shahangian; J. Tavakoli Use of dimethyl ether (DME) as a diesel fuel alternative has been increased due to the unique combustion characteristics of this oxygenated fuel. We have investigated performance and combustion characteristics of a naturally aspirated diesel...

... the creation of different configurations in a simple and flexible manner. This makes possible to compare the performance between different designs of individual components or complete secondary air systems as well as integrate them directly in whole engine performance models. The modeling is validated against...

... flow patterns about and through such ACSCs is essential if their performance is to be improved under these conditions. The present numerical study models the air flow field about and through a particular ACSC. The performance of the fans is modeled with the aid of a novel numerical approach known...

...Nirendra N. Mustafi; Robert R. Raine Investigations on alternative fuels for internal combustion engines are regarded as one of the major research areas for the age. Engine simulation tools can play an important role in such investigations without performing the experimental works. It usually saves...

... that these statistical correlations and curve fits are usually based on experimental cascade data that actually display a fairly large scatter, resulting in a relatively high degree of uncertainty. This usually leads to substantial differences between the calculated and actual performances of a given gas turbine engine...
