Experimental and Numerical Investigation on Ignition and Horizontal Flame Spread for Recycled Plastic Pellets

Fire and Materials, EarlyView.
ABSTRACT Fires in recycling facilities are known for producing noxious fumes, having high heat release rates (HRRs), being difficult to extinguish and causing significant devastation to business operations. This research aims to provide experimental data and numerical models from which performance‐based designs can be developed for recycling facilities.

Performance and Exhaust Emissions of a Gas-Turbine Engine Fueled with Biojet/Jet A-1 Blends for the Development of Aviation Biofuel in Tropical Regions

Energies, 2020
Biofuels as alternative fuels in today’s world are becoming increasingly important for the reduction of greenhouse gases. Here, we present and evaluate the potential of a new alternative fuel based on the conversion of medium-chain fatty acids to biojet (

Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

Land Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Modeling nitrogen species from ammonia reciprocating engine combustion in temperature-equivalence ratio space

Applications in Energy and Combustion Science
This paper explores nitrogen species formation in temperature (T)-equivalence ratio (ϕ) space under internal combustion engine-relevant conditions using zero-dimensional modeling. The analysis reveals that N2O and NO are formed in a much larger region of

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

On the One-dimensional Stability of Viscous Strong Detonation Waves [PDF]

, 2003
Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations.

Propagation Characteristics of Aluminum/Propylene Oxide Multiphase Cloud Explosion With Different AlH3 Ratios and Initiation Energies

Safety Science and Technology, EarlyView.
Explosion process of propylene oxide (PO)/Al/AlH3/air was investigated. The PO/Al/AlH3/air multiphase clouds under strong ignition detonation have reached a quasi‐detonation state. ABSTRACT Fuel‐air explosives (FAE) are an important source of explosion energy. The density advantage of aluminum hydride (AlH3) dust is obvious compared with that of liquid

Effects of natural gas admission location and timing on performance and emissions characteristics of LPDF two-stroke engine at low load

Case Studies in Thermal Engineering
Low-pressure gas-admission marine two-stroke engines have significant potential for reducing emissions in the shipping industry. However, they exhibit poor combustion quality under low-load conditions, leading to lower thermal efficiency and high levels ...

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

Journal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Effect of flue gas recirculation on the formation of unburned hydrocarbons in oxy-fuel and air flames in a semi-industrial scale burner

Fuel Processing Technology
Oxy-fuel combustion is a promising technology for reducing CO2 emissions in the energy sector. In this process, nitrogen from air is replaced with CO2, to ensure the purity of CO2 in the flue gas, altering the properties of the oxidizer.
