Analysis of soot formation in a lab-scale Rich-Quench-Lean combustor using LES with tabulated chemistry

Pachano-Prieto, Leonardo Manuel; Kalbhor, Abhijit; Mira, Daniel; Van-Oijen, Jeroen (Elsevier, 2024)

[EN] A numerical study of the effects of air dilution on soot formation and particle dynamics in a lab-scale rich-quench-lean (RQL) combustor is presented using large-eddy simulations (LES) with tabulated chemistry. The ...
Crystalline phase transition in as-synthesized pure silica zeolite RTH containing tetra-alkyl phosphonium as organic structure directing agent

Martinez-Ortigosa, Joaquin; Millán, Reisel; Simancas, Jorge; Hernández-Rodríguez, Manuel; Vidal Moya, José Alejandro; Jorda Moret, Jose Luis; Martineau-Corcos, Charlotte; Sarou-Kanian, Vincent; Boronat Zaragoza, Mercedes; Blasco Lanzuela, Teresa; Rey Garcia, Fernando (The Royal Society of Chemistry, 2024-01-03)

[EN] The choice of structure directing agents (SDAs) in zeolite synthesis significantly impacts the arrangement of active sites, thereby influencing the stabilization of reaction intermediates with profound implications ...
Deploying deep Solanaceae domestication and virus biotechnology knowledge to enhance food system performance and diversity

Pasin, Fabio; Uranga, Mireia; Charudattan, Raghavan; Kwon, Choon-Tak (Oxford University Press, 2024-09-01)

[EN] Our knowledge of crop domestication, genomics, and of the plant virosphere unevenly represents the taxonomic distribution of the global biodiversity, and, as we show here, is significantly enriched for the Solanaceae. ...
Evidences of persisting thermal structures in Couette flows

Alcántara-Ávila, Francisco; Gandía-Barberá, Sergio; Hoyas, S (Elsevier, 2019-04)

[EN] DNS of passive thermal turbulent Couette flow at several friction Reynolds numbers (180, 250, and 500), and the Prandtl number of air are presented. The time averaged thermal flow shows the existence of long and wide ...
Influence of the zeolite support on the catalytic properties of confined metal clusters: a periodic DFT study of O2 dissociation on Cu-n clusters in CHA

Gallego-Rodríguez, Mario; Corma Canós, Avelino; Boronat Zaragoza, Mercedes (The Royal Society of Chemistry, 2022-12-14)

[EN] The catalytic properties of sub-nanometer Cun clusters are modified by interactions with inorganic supports used for their stabilization. In this work, the reactivity towards O2 dissociation of Cu5 and Cu7 clusters ...
LES study on spray combustion with renewable fuels under ECN Spray-A conditions

Mira Martínez, Daniel; Pérez-Sánchez, Eduardo J.; Surapaneni, Anurag; Benajes, Jesús; García-Oliver, José M; Pastor Enguídanos, José Manuel; De Leon-Ceriani, Daiana (American Society of Mechanical Engineers (ASME), 2021-10-15)

[EN] Poly-Oxymethylene Dimethyl Ethers (OMEx) are being intensively investigated because of their potentially renewable synthesis path, which make them suitable as liquid fuels for low-carbon transport applications. In the ...
Optical absorption of defect chalcopyrite and defect stannite ZnGa2Se4 under high pressure

Gomis, O.; Vilaplana Cerda, Rosario Isabel; Pérez-González, E.; Ruiz-Fuertes, J.; Rodríguez-Hernández, P.; Muñoz, A.; Errandonea, D.; Segura. A.; Santamaría-Pérez, D.; Alonso-Gutiérrez, P.; Sanjuan, M.L.; Tiginyanu, I.M.; Ursaki, V.V.; Manjón, Francisco-Javier (Elsevier, 2023-04-05)

[EN] Optical absorption measurements at high pressure have been performed in two phases of the ordered -vacancy compound (OVC) ZnGa2Se4: defect stannite (DS) and defect chalcopyrite (DC). The direct bandgap energy of both ...
