1. 1. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Aryan Delir; [2022]
   Keywords : gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

   Abstract : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

3. 2. Heavy-Duty Spark-Ignited Single Cylinder Engine Fueling System

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Rohan Sharad Kittur; [2018]
   Keywords : Fueling system; heavy-duty; spark-ignited; single cylinder engine; aftermarket engine control unit; fuel-air mixture safety; bränslesystem; tunga fordon; tändstiftsantändning; encylinder motor; eftermarknadsmotorstyrenhet; bränsle-luft blandningssäkerhet;

   Abstract : Forskning inom motorutveckling bedrivs för att möta kommande emissionskrav och samtidigt minska bränsleförbrukningen. Kommande förbud mot dieseldrivna fordon planeras i flera städer runt om i världen. Alternativa bränsle som exempelvis naturgas ses som en lovande ersättning även för tunga fordon. READ MORE

4. 3. Hydraulic Characterization of Diesel Engine Single-Hole Injectors

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Javier Arco Sola; [2015]
   Keywords : ;

   Abstract : Due to world trend on the emission regulations and greater demand of fuel economy,the research on advanced diesel injector designs is a key factor for the next generation diesel engines. For that reason, it is well established that understanding the effects of the nozzle geometry on the spray development, fuel-air mixing, combustion and pollutants formation is of crucial importance to achieve these goals.
