One way of representing the size and shape of biomass particles in combustion modeling
(Elsevier, 2017-06-29)
This study aims to provide a geometrical description of biomass particles that can be used in combustion models. The particle size of wood and herbaceous biomass was compared using light microscope, 2D dynamic imaging, ...
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 ...

Modeling the influence of potassium content and heating rate on biomass pyrolysis
(Elsevier, 2017-03-14)
This study presents a combined kinetic and particle model that describes the effect of potassium and heating rate during the fast pyrolysis of woody and herbaceous biomass. The model calculates the mass loss rate, over a ...
An experimental study on the key fretting variables for flexible marine risers
(Elsevier, 2017-07-02)
This paper presents an experimental investigation into the effects of contact
conformity, contact pressure and displacement amplitude on the gross-slip fretting behaviour grease-lubricated cylinder-on-flat contacts in the ...
A physically-based constitutive model for high temperature microstructural degradation under cyclic deformation
(Elsevier, 2017-03-23)
This paper presents a dislocation-mechanics cyclic viscoplasticity model which incorporates the key physical micro-mechanisms of strengthening and softening for high temperature deformation of 9Cr steels. In particular, ...
The effect of the beta phase on the micromechanical response of dual-phase titanium alloys
(Elsevier, 2017-03-24)
This paper investigates the role of beta phase on the micro-mechanical behaviour of dual-phase titanium alloys, with particular emphasis on the phenomenon of cold dwell fatigue, which occurs in such alloys under room ...
Influence of material inhomogeneity on the mechanical response of a tempered martensite steel
(SAGE Publications, 2017-01-13)
Failure in steel weldments operating at high temperatures often occurs in the heat-affected zone adjacent to the weld. Such failures can be a result of material inhomogeneity within the heat-affected zone and in the case ...
Experimental investigation, numerical modelling and multi-objective optimisation of composite wind turbine blades
(Taylor & Francis, 2017-05-24)
Static load and modal testing of two blades from a 15 kW wind turbine is presented. The two blades are made from glass fibre-reinforced polypropylene, one of which has been reinforced with additional carbon fibre plies. ...
Rotational moulding of PEEK polymer liners with carbon fibre/PEEK over tape-placement for space cryogenic fuel tanks
(Elsevier, 2017-07-15)
PEEK polymers are investigated as replacement materials for metallic liners in composite overwrapped pressure vessels (COPVs) for fuel tank applications in space. A novel, integrally heated, rotational moulding tool has ...
