The efficiency of the application of high-emissivity coatings on the furnace walls in steam cracking technology can only be evaluated on the asis of a description of radiative heat transfer distinguishing between the frequency bands. To this end, a non-grey gas radiation model based on he exponential wide band model (EWBM) has been developed and applied in(More)
A three-dimensional mathematical model has been developed for the simulation of flow, temperature and concentration fields in the radiation section of industrial scale steam cracking units. The model takes into account turbulence–chemistry interactions through the Eddy Dissipation Concept (EDC) model and makes use of Detailed Reaction Kinetics (DRK), which(More)
A Lagrangian-Eulerian methodology is developed for the numerical simulation of a gas-solid reactive flow. The SO2-NOx Adsorption Process (SNAP) is taken as a test case. A three-dimensional time dependent simulation is performed. A notional particle based Monte-Carlo algorithm is used to solve the transported composition Probability Density Function (PDF)(More)
The ongoing research effort presented here aims at finding the most time-effective solver for reactive flow problems with strong volumetric expansion, and strong feedback effects of the reactions on the flow. This solver has to perform steady-state simulations of important chemical processes involving multiphase flow and detailed kinetics with minimal total(More)
Liquid lead-bismuth eutectic (LBE) is an important candidate to become the primary coolant of future, generation IV, nuclear fast reactors and Accelerator Driven System (ADS) concepts. One of the main challenges with the use of LBE as a coolant is to avoid its oxidation which results in solid lead oxide (PbO) precipitation. The chemical equilibria governing(More)
A unique normalized radial pressure profile characterizes the bed of a gas-solid vortex reactor over a range of particle densities and sizes, solid capacities, and gas flow rates: 950–1240 kg/m, 1–2 mm, 2 kg to maximum solids capacity, and 0.4–0.8 Nm/s (corresponding to gas injection velocities of 55–110 m/s), respectively. The combined momentum(More)
