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 ... -
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, ...
