A new solution approach for discrete adjoint Reynolds-averaged Navier–Stokes equations is suggested. The approach is based on a combination of algebraic multigrid and defect correction. The efficient interplay of these two methods results in a fast

Torrefaction describes a thermal treatment of biomass in order to obtain a solid product with more or less coal-like properties. Therefore a mild pyrolysis in an oxygen-free atmosphere is applied. In this work beechwood was used as feedstock because

The oxyfuel combustion technology has gained increased interest as a promising option for carbon capture and storage (CCS) in the last few years. The substitution of air by a mixture of recylced flue gas (RFG) and oxygen, however, is followed by chan

In this paper, we describe the implementation of an AMG solver for a hybrid cluster that exploits distributed and shared memory parallelization and uses the available GPU accelerators on each node. This solver has been written by using LAMA (Library

This work presents the trends in NOx emissions during pulverized fuel (PF) oxy-fuel combustion using the coal combustion test facility (100 kW) at RWTH Aachen University. In this facility, three modes of pulverized coal combustion have been considere

For combustion in an CO 2 /O 2 atmosphere, known as oxy-combustion, altered combustion rates have to be expected. Previous investigations reported that this can be explained not only with the different thermophysical and radiative properties, but als

The cooperative project OXYCOAL-AC aims at the development of a zero-CO2-emission coal combustion process for power generation. The scope of the research comprises a multitude of aspects. This article focuses on membrane-based air separation modules

Given the continued difficulty of developing geometric multigrid methods that provide robust convergence for unstructured discretizations of compressible flow problems in aerodynamics, we turn to algebraic multigrid (AMG) as an alternative with the p

Flameless combustion is a well known measure to reduce NO x emissions in gas combustion but has not yet been fully adapted to pulverised coal combustion. Numerical predictions can provide detailed information on the combustion process thus playing a

This work is to clarify the underlying mechanisms of burning pulverised coal in a mixture of CO2/O2CO2/O2. The performance of two different burner designs, single central orifice-type (SCO) and single annular orifice-type (SAO), under oxycoal conditi
