flow in the first two-stage of v 94.2 gas turbine is simulated numerically. in this turbine, the second stator is clocked relative to the first stator to different positions. steady-state analysis was carried out by varying the circumferential relative position of the consecutive stator vanes to study the effects of the clocking on turbine performance. a density based compressible inviscid flow...

Aiming at the problems existing in fault diagnosis of Distributed micro gas turbine, a kind of new information system frame of fault Diagnosis on Distributed micro gas turbine is proposed in this paper. The consumers and the manufactures contact with each other through Internet, share the corresponding data of the Distributed Micro-turbine, and diagnose and solve the faults together. Through th...

due to increasing expansion of energy consumption and also the decrease and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. the presentresearch investigates suitable possibility of exploiting wind energy to create wind power stationin soltanieh zone of za...

Present day jet engines are controlled and monitored by a series of hydraulic, fueldraulic, electrical and pneumatic sub-systems known as the Full Authority Digital Engine Controller (FADEC). At the heart of the FADEC lies a centralised Electronic Engine Controller (EEC) responsible for control and safety of the wider engine system. It has long been postulated that a distributed EEC would contr...

Two power plant schemes that reduce CO2 emission and employ natural gas reforming were analyzed and discussed. The first one integrates natural gas reforming technology for efficiency improvement with an oxy-fuel combined power system (OXYF-REF), with water as the main work fluid. The reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel wit...

This paper adds an exergy analysis of the novel SOLRGT solar-assisted power generation system proposed and described in detail in Part I of this study (Zhang and Lior, 2012, “Use of Low/Mid-Temperature Solar Heat for Thermochemical Upgrading of Energy, Part I: Application to a Novel Chemically-Recuperated Gas-Turbine Power Generation (SOLRGT) System,” ASME J. Eng. Gas Turbines Power, Accepted. ...

Natural gas is currently the natural substitute of petroleum as an energy source, since the foreseen ending up of this latter in the next decades. As a matter of fact, natural gas is easier to handle, less dangerous to be transported, somehow environmentally more friendly. The gas ducts operate with large flow rates over very long distances at high pressures, which are usually lowered in proxim...

The paper examines design and operating data of current concentrated solar power (CSP) 10 solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas 11 (NG) and with or without thermal energy storage (TES). The study then reviews the novel trends to 12 produce better ratio of solar field power to electric power, better capacity factor, better matching of ...

In this paper, model predictive control (MPC) strategy is implemented to a GE9001E gas turbine power plant. A linear model is developed for the gas turbine using conventional mathematical models and ARX identification procedure. Also a process control model is identified for system outputs prediction. The controller is designed in order to adjust the exhaust gas temperature and the rotor speed ...
