Correlation effects between turbulence and the conversion rate of pulverized char particles
Krüger, Jonas; Haugen, Nils Erland L; Løvås, Terese (Journal article; Peer reviewed, 2017)The effect of turbulence on heterogeneous reactions on the surface of char particles embedded in a turbulent oxidizer, consisting of oxygen and carbon-dioxide, is in this work studied numerically. It is shown that for a ... -
Numerical Investigation of the Effect of Flow Turbulence on Heterogeneous Reaction Rates
Krüger, Jonas (Doctoral theses at NTNU;2017:116, Doctoral thesis, 2017)In this thesis, the effect of turbulence on heterogeneous reactions is investigated. After a short introduction into the state-of-the-art of turbulent combustion modelling, an overview over the numerical methods and models ... -
Numerical Study of Hydrogen Inhibition of Char Gasification Using Detailed Hetero- and Homogeneous Chemical Kinetics
Lazar, Joanna; Haugen, Nils Erland L; Krüger, Jonas; Szlek, Andrzej (Journal article; Peer reviewed, 2016)It has been known for a long time that hydrogen in the gas phase tends to inhibit gasification of char at low and intermediate temperatures. At higher temperatures, however, there are indications that hydrogen may speed ... -
The effect of turbulence on mass transfer rates of small inertial particles with surface reactions
Haugen, Nils Erland Leinebø; Krüger, Jonas; Mitra, Dhrubaditya; Løvås, Terese (Journal article; Peer reviewed, 2017)The effect of turbulence on the mass transfer between a fluid and embedded small heavy inertial particles that experience surface reactions is studied. For simplicity, the surface reaction, which takes place when a gas ... -
Thermophoresis and its effect on particle impaction on a cylinder for low and moderate Reynolds numbers
Haugen, Nils Erland L; Krüger, Jonas; Aarnes, Jørgen Røysland; Karchniwy, Ewa Malgorzata; Klimanek, Adam (Peer reviewed; Journal article, 2021)The effect of thermophoresis on the impaction of particles on a cylinder is investigated for different particle sizes, particle conductivities, temperature gradients and for Reynolds numbers between 100 and 1600. This is ...
