Experimental Analysis of Combustion and Emission Characteristics of a Diesel Engine Using Diesel-Biodiesel-Methanol Blends With Cetane Enhancer Additive Under Pilot Injection Mode. [PDF]

open access: yesGlob Chall
The work represented in the manuscript is based on resolving the major issue of increased smoke emissions under pilot injection mode while maintaining the core benfits of it, that is, lower nitrogen oxides (NOx) emissions and improved fuel economy. This was achieved by inclusion of methanol and cetane enhancer (CE) in the base fuel.

A new multi-dimensional flamelet generated manifolds approach for approximating partially premixed flame structure

open access: yesJournal of Thermal Science and Technology, 2015
A new multi-dimensional flamelet generated manifolds(MFM) approach is proposed based on solving multi-dimensional flamelet equation set in mixture fraction Z and normalized flamelet progress variable c coordinate, to capture both non-premixed and ...

Study on Combustion Oscillation of Premixed Flame with Pilot Fuel at Elevated Pressures

open access: yesJournal of Thermal Science and Technology, 2009
Acoustically-coupled combustion oscillation is studied for premixed flame with pilot fuel to be used in gas turbine combustors. Premixed gas is passed through swirl vanes and burnt with the centrally injected pilot fuel.

Effect of Premixed n-Butanol Ratio on the Initial Stage of Combustion in a Light-Duty Butanol/Diesel Dual-Fuel Engine

open access: yesEnergies, 2020
The impact of premixed n-butanol mixture on the heat release rate was investigated based on a modified light-duty diesel engine. The results show that reactivity stratification is formed in the cylinder through n-butanol port fuel injection (PFI) and ...

A Lagrangian-based flame index for the transported probability density function method

open access: yesTheoretical and Applied Mechanics Letters, 2022
We propose a new flame index for the transported probability density function (PDF) method. The flame index uses mixing flux projections of Lagrangian particles on mixture fraction and progress variable directions as the metrics to identify the ...

Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]

open access: yes, 2012
This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.
