Hydrodynamic effects of use of eductors (Jet-Mixing Eductor) for water inlet on circular tank fish culture
Venegas, Pablo A.; Narváez, Ana; Arriagada, Amilcar E.; Llancaleo, Katherine A. (2014)Trials were conducted in circular tanks used in aquaculture (1.2 m diameter and 0.4 of useful depth) in order to evaluate the effect of different water injection devices on the tangential velocity of the water, its uniformity ... -
Mean field theory studies of surface reactions on disordered substrates
Cortés, Joaquı́n; Narváez, Ana; Puschmann, Heinrich; Valencia, Eliana (2003)A mean field theory (MFT) in the site and pair approximations of a surface reaction system on a disordered substrate showing geometric heterogeneity is proposed, characterizing the substrate completely through the set {qi} ... -
Shape-selectivity effects in syngas-to-dimethyl ether conversion over Cu/ZnO/Al2O3 and zeolite mixtures: Carbon deposition and by-product formation
Montesano, R.; Narváez, Ana; Chadwick, D. (2014)The conversion of syngas into dimethyl ether has been studied over physical mixtures of a Cu/ZnO based catalyst and a zeolite. Theta-1, ZSM-23, ferrierite, ZSM-5 and mordenite were used. The zeolites were separated after ... -
Small-medium scale polygeneration systems: Methanol and power production
Narváez, Ana; Chadwick, D.; Kershenbaum, L. (2014)The feasibility and attractiveness of the integrated production of chemicals and electrical power is dependent upon on the nature of the products and their demands. This study focuses on the small-to-medium scale combined ...
