    • CO2 gasification reactivity of char from high-ash biomass 

      Phounglamcheik, Aekjuthon; Vila, Ricardo; Kienzl, Norbert; Wang, Liang; Hedayati, Ali; Broström, Markus; Ramser, Kerstin; Engvall, Klas; Skreiberg, Øyvind; Robinson, Ryan; Umeki, Kentaro (Peer reviewed; Journal article, 2021)
      Biomass char produced from pyrolysis processes is of great interest to be utilized as renewable solid fuels or materials. Forest byproducts and agricultural wastes are low-cost and sustainable biomass feedstocks. These ...

    • The Effects of Pyrolysis Conditions and Feedstocks on the Properties and Gasification Reactivity of Charcoal from Woodchips 

      Phounglamcheik, Aekjuthon; Wang, Liang; Romar, Henrik; Kienzl, Norbert; Broström, Markus; Ramser, Kerstin; Skreiberg, Øyvind; Umeki, Kentaro (Peer reviewed; Journal article, 2020)
      Pyrolysis conditions in charcoal production affect yields, properties, and further use of charcoal. Reactivity is a critical property when using charcoal as an alternative to fossil coal and coke, as fuel or reductant, in ...

    • The effects of Stefan flow on the flow surrounding two closely spaced particles 

      Jayawickrama, Thamali R.; Chishty, Muhammad Aqib; Haugen, Nils Erland L; Bäbler, Matthâus Ulrich; Umeki, Kentaro (Peer reviewed; Journal article, 2023)
      The aim of the work was to study the effects of neighboring particles with uniform Stefan flow in particle–fluid flows. Particle-resolved numerical simulations were carried out for particles emitting a uniform Stefan flow ...

    • The effect of Stefan flow on the drag coefficient of spherical particles in a gas flow 

      Jayawickrama, Thamali R.; Haugen, Nils Erland L.; Bäbler, Matthâus Ulrich; Chishty, Muhammad Aqib; Umeki, Kentaro (Journal article; Peer reviewed, 2019)
