A detailed comparison of ethanol–diesel direct fuel blending to conventional ethanol–diesel dual-fuel combustion

Automotive and Engine Technology
Dual-fuel combustion is a well-known measure to enable the combustion of low-reactivity fuels (LRF) in compression-ignited engines with high thermal efficiency through a pilot injection of a high-reactivity fuel (HRF).

CHEMISTRY-TURBULENCE COUPLING IN A MODEL OF INHOMOGENOUSLY PREMIXED COMBUSTION

TASK Quarterly, 2003
Results of work on an extension of the turbulent flame speed model used for a mathematical description of partially premixed combustion are presented. The approach is based on the concept of internal coupling between the turbulence of the mixed fuel and

Large Eddy Simulation of a Swirl-Stabilized Pilot Combustor from Conventional to Flameless Mode

Journal of Combustion, 2016
This paper investigates flame and flow structure of a swirl-stabilized pilot combustor in conventional, high temperature, and flameless modes by means of a partially stirred reactor combustion model to provide a better insight into designing lean ...

Fuel and combustion stratification study of Partially Premixed Combustion

, 2016
Relatively high levels of stratification is one of the main advantages of Partially Premixed Combustion (PPC) over the Homogeneous Charge Compression Ignition (HCCI) concept. Fuel stratification smoothens heat releaseand improves controllability of this kind of combustion. However, the lack of a clear definition of “fuel and combustion stratifications”

Numerical study of low-emission combustion of NH3-H2-N2 mixtures from partial ammonia decomposition

Ain Shams Engineering Journal
Ammonia (NH3) and hydrogen (H2) are promising non-carbon fuels for the decarbonization of thermal processes through combustion·NH3 can serve as an efficient carrier for H2 through partial decomposition.

Study on combustion performances of partially premixed flame in a micro-combustor with cavity

Case Studies in Thermal Engineering
Combustion characteristics of a partially premixed flame in a micro-combustor with a wall cavity were studied numerically under various conditions (primary air coefficient, α = 0.35, 0.5, and 0.65).
