This paper explores the modeling and simulation of combustion processes in a gas turbine combustor both with and without water injection for NOx control. The combustor can be modeled as a series and/or parallel combinations of perfectly stirred reactors (PSRs) and plug flow reactors (PFRs). Kinetics models require solution of non-linear and stiff ordinary differential equations (ODEs). The CVODE code from Lawrence Livermore National Laboratory can be used for the solution of these ODEs. Here we show that a reduced kinetics set coupled with an Excel callable version of CVODE (as a dynamic link library (dll)) can be used to predict emission trends in combustors. Student use is promoted by using Excel as the pre- and post-processor. Keywords reaction mechanism; gas turbine combustion; modeling; water injection; emissions
Introduction Power generation from gas turbines is seeing increased utilization as the price of natural gas reaches historic lows. The switch to natural gas turbines for power generation is also [...]
