Numerical modelling of flow and transport processes in a calciner for cement production
(2007)Controlling the calcination process in industrial cement kilns is of particular importance because it affects fuel consumption, pollutant emission and the final cement quality. Therefore, understanding the mechanisms of ... -
Numerical modelling of rotating tangential layers (jets) in shells under strong uniform magnetic field
(2010)A numerical study of tangential layers in steady-state magnetohydrodynamic rotating flows is presented using CFD to solve the inductionless governing equations. The analysis considers two basic flow configurations. In the ... -
Numerical modelling of simulated blood flow in idealized composite arterial coronary grafts: Transient flow
(2008)In composite arterial coronary grafts (CACGs), transport phenomena and geometry may considerably alter blood flow dynamics. CACGs aim at revascularizing pathological arteries according to the human anatomy. However, the ... -
Numerical modelling of steel pipelines subjected to severe monotonic and cyclic straining
(2014)Offshore and onshore pipelines may experience extreme loading conditions during their installation and operation, both of monotonic and cyclic nature. Loading actions such as pipeline lateral displacements, tensioning, or ... -
Numerical modelling of the pull-out of hooked steel fibres from high-strength cementitious matrix, supplemented by experimental results
(2010)The paper deals with the numerical modelling of hooked steel fibres embedded in high-strength cementitious matrix. The pull-out of the fibres is first studied by means of accurate three-dimensional models which take into ... -
Numerical simulation of a wall-flow particulate filter made of biomorphic silicon carbide able to fit different fuel/biofuel inputs
(2019)To meet the increasingly strict emission limits imposed by regulations, internal combustion engines for transport applications require the urgent development of novel emission abatement systems. The introduction of biodiesel ... -
Numerical simulation of bending response of reinforced concrete and fibre-reinforced concrete beams
(2008)The aim of this work is to understand the behaviour of members made of fibre reinforced concrete (FRC). The members under study were fibre reinforced concrete beams with no conventional reinforcement, as well as fibre ... -
Numerical simulation of bubble dynamics in response to acoustic disturbances
(1996)The dynamic behavior and the fashion of collapse of a free bubble play a significant role in the phenomenon of single cavitation bubble luminescence (SCBL) and single bubble sono-luminescence (SBSL), in which light is ... -
Numerical simulation of buried steel pipelines under strike-slip fault displacements
(2011)The paper examines the structural response of buried butt-welded steel pipelines, crossing active strike-slip tectonic faults, which are vertical and perpendicular to the pipeline axis. The interacting soil-pipeline system ... -
