SUMMARY:On the conversion of Gas Turbine Combustors – Low Swirl Injection
DESCRIPTION:Lecturer:Joseph Kalyan Raj I.\n Faculty:Department of Aerospace
  Engineering\n Institute:Technion – Israel Institute of Technology\n Loc
 ation:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n A
 bstract: \n Details: \n The research work will discuss investigations into
  the characteristics of Low Swirl Injector (LSI) technique as a viable mod
 ification to be used in the conversion of liquid fuelled aero-engines to g
 aseous fueled gas turbines. Implementation of LSIs as an effective fuel in
 jection method for in-operation gas turbines opens the possibility of conv
 ersion of liquid-fuelled jet engines to fuel-flexible aeroderivative gas t
 urbine power plants. Low Swirl Injectors (LSIs) can be used for ultra-low 
 emissions operation of gas turbines and promise to be a potential optimiza
 tion tool in the conversion of jet engines to aeroderivative gas turbines\
 , since their implementation requires minimal modifications to the combust
 or geometry.\nThe present study explores the fluid dynamics aspects of an 
 LSI system that has been studied using a variable swirl burner\, developed
  as a part of the study. The study included combustion experiments and col
 d-flow numerical simulations\, in order to determine the limits of operati
 on of the burner in the LSI regime. Further\, a novel swirl number has bee
 n developed to better characterize the low swirl characteristics of the LS
 I technique. The LSI swirl number looks promising towards developing a dee
 per understanding of the physics of the LSI method\, and opens up the poss
 ibility for new approaches to numerical modelling of LSI flames. The ultra
 -low emissions burning of LSI flames have been established in the experime
 nts\, thus showing with certainty that the Low Swirl Injection method has 
 potential as a viable method for gas turbine combustor modification.
