Computational fluid dynamic simulations of thermochemical conversion of pulverized biomass in a dilute flow using spheroidal approximation
Guo, Ning; García Llamas, Ángel David; Li, Tian; Umeki, Kentaro; Gebart, Rikard; Løvås, Terese (Peer reviewed; Journal article, 2020)A drag force model for spheroids, referred as the spheroid model, was implemented in OpenFOAM, in order to better predict the thermochemical conversion of pulverized biomass. Our previous work has found that the spheroid ... -
Eulerian-Lagrangian simulation of pulverized biomass jet using spheroidal particle approximation
Guo, Ning; Li, Tian; Zhao, Lihao; Løvås, Terese (Journal article; Peer reviewed, 2019)Pulverized biomass has great potential to replace coal in many industrial systems such as suspension-firing furnaces and entrained-flow gasifiers. The shape of pulverized biomass deviates significantly from the quasi-spherical ... -
Modelling of reacting multi-phase flow for biomass gasification
Guo, Ning (Doctoral theses at NTNU;2020:103, Doctoral thesis, 2020)Entrained flow gasification of pulverized biomass is considered as one of the potential technology routes to produce syngas, which later can be used to produce second generation of biofuels via Fisher-Tropsch (FT) synthesis. ... -
Performance comparison of organic Rankine cycle (ORC) and CO2 cycle for simultaneous utilization of liquefied natural gas (LNG) cold energy and solar energy
Yu, Haoshui; Guo, Ning; Quoilin, Sylvain; Sin, Gürkan (Chapter, 2021)LNG is a good way to transport natural gas from suppliers to consumers. However, the LNG cold energy is generally lost during the regasification process at the receiving terminals. LNG cold energy can be a great heat sink ... -
Rapid change of particle velocity due to volatile gas release during biomass devolatilization
García Llamas, Ángel David; Guo, Ning; Li, Tian; Gebart, Rikard; Umeki, Kentaro (Peer reviewed; Journal article, 2021)Our earlier study showed significant differences in average particle velocity between simulation and experimental results for devolatilizing biomass particles in an idealised entrained flow reactor [N. Guo et al., Fuel, ... -
Understanding Energy Conversion in Combustion
Lorentzen, Simon Johan (Master thesis, 2021)I dette prosjektet har tre forskjellige modeller for flammer blitt undersøkt: forblandet velblandet reaktor, forblandet fritt-spredene flamme, og ikke-forblandet motstrøms flamme. Målet med prosjekter var å først bestemme ...
