Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is an inflammatory demyelinating disease that is distinct from multiple sclerosis. Initial manifestations of MOGAD that were reported in the literature included optic neuritis, myelitis, brainstem demyelination and encephalitis, with emphasis placed on acute disseminated enceph...

The operating limit and pressure fluctuations of a localized stratified vortex-tube combustor (LSVC) are investigated experimentally by taking methane as fuel at the inlet temperature of 300 K and the combustor pressure of 1 atm over a range of equivalence ratios (0.1-1.0). The combustion modes are distinguished according to the properties of press...

Direct numerical simulation data obtained from two statistically stationary, one-dimensional, planar, weakly turbulent, premixed flames are analyzed in order to examine the influence of flame-generated vorticity on the surface area of the reaction zone. The two flames are associated with the flamelet combustion regime and are characterized by two s...

A computational simulation was performed to predict ash deposition in an industrial scale coal-fired boiler. The single-rate model and the improved nth order model were employed for devolatilization and char reaction with the model constants obtained from PC Coal LAB.(1) Ash particles were deposited on the wall by inertial impaction with the captur...

For the mixing-sensitive reactions, both chemical kinetics and mixing conditions of the reactants determine the distributions of products. The direct quadrature method of moments combining with the interaction by exchange with the mean micro-mixing model (DQMOM-IEM) has been validated for the chemical reacting flows in microreactors. Quite encourag...

The Lagrangian conditional moment closure (CMC) model is applied to combustion simulation of a diesel engine at different load conditions. Calculation is performed by the free open-source computational fluid dynamics (CFD) package, OpenFOAM (Jasak, 1996). In Lagrangian CMC total injected fuel is divided into a given number of fuel groups with each ...

Conditional Moment Closure (CMC) and Conditional Source-term Estimation (CSE) are investigated in a direct side-by-side comparison of the Sandia flames. The objective of the present study is to determine the strengths and weaknesses of each modelling approach given the same initial conditions and computational set-up. The predictions from both CMC ...

This work employs a combination of pressure trace analysis, high-speed optical measurements and laser-based techniques for the assessment of the effects of various post-injection schemes on the soot reduction potential in an optical single-cylinder light-duty diesel engine. The engine was operated under a multiple injection scheme of two pilot and ...

The present study focuses on determining the potential applicability of ammonia (NH3) as a carbon-free alternative fuel through numerical simulations. The combustion and emissions characteristics of premixed NH3-air flame at preheating conditions were numerically investigated. The burning velocity and all species mole fraction were determined using...
