LES and RANS of air and oxy-coal combustion in a pilot-scale facility: Predictions of radiative heat transfer
A.G. Clements,S. Black,János Szuhánszki,Katarzyna Stęchły,A. Pranzitelli,William Nimmo,Mohamed Pourkashanian +6 more
TL;DR: In this paper, the use of large eddy simulation (LES) and Reynolds-averaged Navier Stokes (RANS) models for the prediction of turbulent coal combustion under air and oxyfuel environments in a pilot-scale 250 kWth furnace was evaluated.

Evaluation of the performance and economic viability of a novel low temperature carbon capture process
Paul Willson,George Lychnos,A.G. Clements,Stavros Michailos,Carolina Font-Palma,M.E. Diego,Mohamed Pourkashanian,Joe Howe +7 more
TL;DR: In this paper, a novel Advanced Cryogenic Carbon Capture (A3C) process is developed using low cost but high intensity heat transfer to achieve high CO2 capture efficiencies with a much reduced energy consumption and process equipment size.

Highly resolved flamelet LES of a semi-industrial scale coal furnace
Martin Rieth,Fabian Proch,A.G. Clements,M. Rabaçal,Andreas M. Kempf +4 more
- 01 Jan 2017
TL;DR: In this paper, a large eddy simulation (LES) of a semi-industrial IFRF coal furnace employing the steady flamelet model is presented, where the flamelet table is based on mixture fractions of volatile and char off-gases as well as on enthalpy and scalar dissipation rate.

Evaluation of FSK models for radiative heat transfer under oxyfuel conditions
TL;DR: In this paper, the influence of assumptions in global full-spectrum k-distribution (FSK) models, and whether they are suitable for modelling radiation in computational fluid dynamics (CFD) calculations of oxyfuel combustion, were evaluated.
