Effects of split injection strategy on the combustion, emission and economic performance of the low-octane gasoline fueled MPCI engines

open access: yesEnergy Reports, 2021
Application of diesel fueled partially premixed compression ignition (PPCI) engines are limited due to its excessive pressure rise rate at high load. Multiple premixed compression ignition (MPCI) engines fueled with low octane number gasoline (LON) has ...

The Importance of Thermodynamic Data for Pyrrole Pyrolysis and Combustion Chemistry

open access: yesChemPhysChem, Volume 27, Issue 18, 28 September 2026.
High level ab initio quantum chemical computations with ORCA 6.1.1 are done to derive enthalpy and entropy of formation at 298.15 K for 32 species that include both radicals and stable molecules relevant to the pyrolysis and combustion of pyrrole. The effects of thermochemical data on chemical model performance are assessed.

Effects of porous insertion in a round-jet burner on flame characteristics of turbulent non-premixed syngas combustion

open access: yesCase Studies in Thermal Engineering, 2019
Synthesis gas (Syngas) is a gaseous mixture that consists of 3 species. It is used in creating synthetic natural gas. In this work, the turbulent non-premixed flame of syngas-air combustion in a round-jet burner is numerically investigated. The burner is

Multi‐Phase Heterostructured NiMoN Nanoflower as Bifunctional Separator Coatings for High‐Performance Lithium–Sulfur Batteries

open access: yesBattery Energy, Volume 5, Issue 5, September 2026.
NiMoN nanoflowers are introduced as multifunctional separator coatings for Li–S batteries. The dual‐metal nitride structure offers strong polysulfide adsorption, accelerated redox kinetics, and enhanced Li+ transport. Compared to NiN and Celgard, NiMoN achieves superior cycling stability, lower capacity fading, and excellent rate performance ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

open access: yesApplications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Comparison of Presumed PDF Models of Turbulent Flames

open access: yesJournal of Combustion, 2012
Over the past years, the use of a presumed probability density function (PDF) for combustion progress variable or/and mixture fraction has been becoming more and more popular approach to average reaction rates in premixed and partially premixed turbulent

The Synthesis and Mechanism of AlB2‐KAlF4 Composites Prepared by Self‐Propagating High Temperature Synthesis Method

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
AlB2‐KAlF4 composites were fabricated via SHS using Al and KBF4. Phase evolution, microstructure, and reaction mechanism were characterized. KBF4/Al melting initiates the reaction; BF3‐Al redox yields AlB2 and KAIF4 with distinct morphologies. ABSTRACT Using Al and KBF4 as raw materials, AlB2‐KAlF4 composites were synthesized by self‐propagating high ...
