Coal is the most abundant fossil fuel and widely used as an energy source for combustion gasification. Both experimental methods computational tools are required development of new advanced, innovative clean coal technologies systems. In particular, 3D fluid dynamics (CFD) simulations can provide detailed local global information on interaction dynamics, mixing, heterogeneous homogeneous chemical reactions even complex systems such combustors, gasifiers, or reactors. The predictive...
Fully-resolved simulations of the heating, ignition, volatile flame combustion and char conversion single coal particles in convective gas environments are conducted compared to experimental data (Molina Shaddix, 2007). This work extends a previous computational study (Tufano et al., 2016) by adding significant level model fidelity generality, particular with regard particle interior description heterogeneous kinetics. The considers elemental analysis given interpolates its properties linear...
Strained two-phase pulverised coal flames in a counterflow configuration are investigated numerically. Three operating conditions with different coal-to-primary-air ratios and inlet velocities were evaluated order to establish flame regimes. At first, the flow of fully resolved reference cases is calculated solving transport equation for species directly evaluating reaction rates. Different structures identified using heat release rate chemical explosive mode as markers, showing that complex...
This work focuses on the impact of devolatilization and char combustion mode modelling structure a large-scale, biomass coal co-fired flame using large eddy simulations. The framework previously developed for simulation in large-scale facilities is extended capabilities. An iterative procedure used to obtain kinetics test-case specific fuels heating conditions. achieved by calibrating model constants two empirical models: single first-order distributed activation energy model. reference data...
In transonic turbine stages, the exit static pressure field of vane is highly non-uniform in pitchwise direction. The rotor traverses periodically this and large fluctuations are observed around section. As a consequence blade submitted to significant variations its aerodynamic force. This contributes high cycle fatigue may result unexpected failure. paper an existing stage section redesigned view reducing stator interaction, particular unsteady forcing. first step redesign profile reduce...
