The objective of this work is to investigate the turbulent reacting flow in a three dimensional combustor with emphasis on the effect of inlet swirl flow through a numerical simulation. Flow field is analyzed using the SIMPLE method which is known as stable as well as accurate in the combustion modeling, and the finite volume method is adopted in solving the radiative transfer equation. In this...

Micro-cogeneration with locally produced biogas from waste is a proven technique for supporting the decarbonization process. However, strongly variable composition of can make its use in internal combustion engines quite challenging. Dual-fuel offer advantages over conventional SI and diesel engines, but there are still issues to be addressed, such as low-load thermodynamic efficiency nitrogen ...

A detection method of lean blowout in a laboratory-scale premixed gas-turbine model combustor has been proposed from a view point of nonlinear dynamics. The translation error, which quantifies the degree of the parallelism of trajectories in the phase space constructed from the time-series data of the combustion-chamber pressure fluctuations, is used as a detector in this work. The dynamic beha...

Gas flaring is the burning process of unwanted raw natural gas (NG) that cannot be processed during oil and extraction operations. This research work aims to continue with experimental prototyping validation a combustion chamber configuration run low methane number (MN) fuels down 35 2 MW internal engine (ICE) fuelled pre-chamber. As opposed solutions available in market for aforementioned type...

This is a clear and well written paper that provides a detailed account of laboratory experiments of water vapor release from a collection of different biomass fuel types. The results from 16 experiments conducted in a combustion chamber show the amount of water vapor released as a ratio to the CO/CO2 combustion efficiency. This paper provides a nice contribution to the fire sciences community ...

Particulate Matter (PM) is one of the major harmful substances in diesel exhaust gas. Technologies like the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) have been positioned at the exhaust to reduce the quantity of harmful substances released to the environment. This paper highlights the factors that affect combustion in diesel engines and the potential of the introductio...

The aeroderivative gas turbine is widely used as it demonstrates many advantages. Adding hydrogen to natural fuels can improve the performance of combustion. Following this, effects enrichment on combustion characteristics were analyzed in an combustor using CFD simulations. numerical model was validated with experimental results. conditions constant mass flow rate and energy input studied. res...

Traditional technologies of solid fuels incineration account for higher level of pollutant in comparison with incineration of liquid and gas fuels. However the fraction of heat and electric power generated at coal fired thermal power plants will increase and by 2020 will have exceeded 50%. Plasma activation promotes more effective and environmental friendly power coals incineration [1]. Effecti...
