Effects of several types of biomass fuels on the yield, nanostructure and reactivity of soot from fast pyrolysis at high temperatures
(Elsevier, 2016-03-24)
This study presents the effect of biomass origin on the yield, nanostructure and reactivity of soot. Soot was produced from wood and herbaceous biomass pyrolysis at high heating rates and at temperatures of 1250 and 1400 ...
Secondary comminution of wood pellets in power plant and laboratory-scale mills
(Elsevier, 2017-03-14)
This study aims to determine the influence of mill type and pellet wood composition on particle size and shape of milled wood. The size and shape characteristics of pellets comminuted using power plant roller mills were ...
Simulation of turbulent flow in a rapid compression machine: Large Eddy Simulation and computationally efficient alternatives for the design of ignition delay time experiments
(Elsevier, 2018-07-05)
Rapid compression machines (RCMs) are widely used by the fuel research community to provide engine-relevant conditions to study ignition delay time (IDT), which is a crucial target for validating chemical kinetic mechanisms ...
Effect of microwave and thermal co-pyrolysis of low-rank coal and pine wood on product distributions and char structure
(American Chemical Society, 2019-07-07)
Direct conversion of a low-rank coal into valuable chemicals or improving its char’s coking value became very demanding goals in coal utilization strategies. In this work, the co-pyrolysis of a low-rank lignite coal and ...
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)
In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ...
A finite element study of microstructure-sensitive plasticity and crack nucleation in fretting
(Elsevier ScienceDirect, 2011)
This paper is concerned with finite element modelling of microstructure-sensitive plasticity and crack initiation in fretting. The approach adopted is based on an existing method for microstructure-sensitive (uniaxial) ...
Microstructure-sensitive prediction and experimental validation of fretting fatigue
(Elsevier ScienceDirect, 2013-06-03)
This paper is concerned with the development of a micro-mechanical methodology for prediction of fretting fatigue crack nucleation life and short crack propagation. The methodology employs critical accumulated plastic slip ...
Micromechanical modelling of fatigue crack nucleation in stents
(Bioengineering In Ireland Conference 2012, 2012)
A finite element based micro-mechanical methodology for cyclic plasticity and fatigue crack initiation in cardiovascular stents is presented. The methodology is based on the combined use of a (global) three-dimensional ...
A review of the integrity of metallic vehicle armour to projectile attack
(SAGE Publications, 2018-02-28)
This article presents a review of engineering and design aspects relevant to the mechanical and structural integrity of military vehicular armour, including materials-related technologies. Theoretical, experimental and ...
Gross slip fretting wear performance of a layered thin W-DLC coating: damage mechanisms and life modelling
(Elsevier ScienceDirect, 2011)
Fretting damage, in the form of wear and fatigue-cracking, is a common cause for concern in a wide range of dynamically loaded mechanical joints, and consequently, control of the rates of such damage is commonly addressed ...
