“…The high temperature of the combustion process impacts the NO production rate and mole fraction which can be observed in Finally based on the numerical results the NO concentration (which is the main NOX component in hot combustion gasses) produced by the engine running on kerosene checks 256 ppm compared to 186 ppm produced by the engine running on the FWE. Clearly the quantitative results of NO production are overestimated when comparing to experimental data given in [25,26]. As explained above, qualitative results are not the aim of the proposed numerical model.…”

The innovative use of the Fuel-Water emulsion in a small gas turbine for distributed energy generation is proposed. The FWE in this situation is considered as a nonhomogeneous mix of water and fuel, where water is a dispersed phase in the continuous fuel phase with an addition of surfactants. The Fuel-Water emulsion has a great mainly due to two mechanisms: temperature reduction due to heat absorption by the water phase and enhanced homogeneity of the fuel-air mixture due to micro-explosion of the superheated water phase inside the emulsion droplet. Proposed paper presents theoretical background on Fuel-Water emulsion combustion mechanism. Finally initial results of numerical research of fuel-water emulsion injection to miniature gas turbine are presented. Theoretical predictions of NOX pollutant emissions are compared with accuracy of the gas analyzer planned to be used during experimental research.

“…Five engine rotational speeds are considered in this article: 40, 60, 80, 100, 120 k rpm. Based on experimental data from GTM-120 engine bench testing [7], following mass flows are calculated: The impact of variable geometry dilution zone hole area is calculated for four residual dilution holes areas: 90, 70, 50 and 30%. It is assumed that the coverage of dilution holes area does not impact the pressure distribution inside combustor.…”

The aim of this article is to present the results of theoretical studies regarding the use of variable geometry hot section of a miniature gas turbine. The variable geometry combustor and variable area nozzle concepts for GTM-120 miniature jet engine are presented in particular. Recent trends of propulsion system size reduction, low-emission combustion and improved fuel efficiency have been considered. A system of variable geometry combustor and variable area nozzle has been proposed as solution. The basic zero-dimensional analytical models for variable geometry combustor and variable area nozzle are developed. Chemkin based model shows significant NOX/CO emissions reduction and combustor outlet enthalpy increases with the use of variable geometry combustor chamber. The analytical model of the variable area nozzle has been proposed. It shows turbine effectiveness increase across its operating range by raising the compressor working line. As a result, noticeable turbine stage efficiency increase has been obtained. Finally, physical implications and future work plans regarding variable geometry hot section of miniature gas turbines are discussed.
