... blowout operability of gas turbines. Flame stratification was achieved by dividing the incoming reactants into primary and secondary streams of different oxygen fractions (OF). The effects of primary and secondary OFs (primary OFs: 60%, 50%, and 30%; and secondary OFs: 60%, 50%, 40%, and 30%) were...

...Nick Petro; Felipe Lopez Aeroderivative gas turbines have their combustion set points adjusted periodically in a process known as remapping. Even turbines that perform well after remapping may produce unacceptable behavior when external conditions change. This article introduces a digital twin...

...Vaibhav Malhotra; W. E. Lear; J. R. Khan; S. A. Sherif A life cycle cost analysis was performed to compare life cycle costs of a novel gas turbine engine to those of a conventional microturbine with similar power capacity. This engine, called the high-pressure regenerative turbine engine (HPRTE...

...Wensheng Lin; Meibin Huang; Hongming He; Anzhong Gu A novel transcritical Rankine cycle is presented in this paper. This cycle adopts CO 2 as its working fluid with exhaust from a gas turbine as its heat source and liquefied natural gas (LNG) as its cold sink. With CO 2 working transcritically...

...T. Srinivas; A. V. S. S. K. S. Gupta; B. V. Reddy Biomass gasification involves the production of a gaseous fuel by partial oxidation of a solid fuel. Clean synthesis (syn) gas, produced from partial combustion of biomass, can be burnt in a gas turbine combustion chamber to run a biomass based...

...Joseph J. Boza; William E. Lear, Ph.D.; S. A. Sherif, Ph.D. A thermodynamic performance analysis was performed on a novel cooling and power cycle that combines a semiclosed gas turbine called the high-pressure regenerative turbine engine (HPRTE) with an absorption refrigeration unit. Waste heat...

...Farhad Behafarid; Mehdi N. Bahadori The power output of gas turbines (GT) reduces greatly with the increase of the inlet air temperature. This is a serious problem because gas turbines have been used traditionally to provide electricity during the peak power demands, and the peak power demands...
