Abstract Background Empty fruit bunch (EFB) has many advantages, including its abundance, the fact that it does not require collection, and year-round availability as a feedstock for bioethanol production. But before significant costs incurred in ethanol production from lignocellulosic biomass can be reduced, an efficient sugar fractionation technology to developed. To end, present study, NaOH-catalyzed steam pretreatment process was applied order produce EFB more efficiently. Results The...
To predict double-emulsion formation in a capillary microfluidic device, ternary diffuse-interface model is presented. The of double emulsions involves complex interfacial phenomena three-phase fluid system, where each component can have different physical properties. We use the Navier-Stokes/Cahn-Hilliard for general hydrodynamics coupled with thermodynamics phase field variables. Our predicts important features which was observed experimentally by Utada et al. [Utada al., Science, 2005,...
A micromixer is one of the most important components for a chemical and/or diagnostic analysis in microfluidic devices such as micro-total-analysis-system and lab-on-a-chip. In this paper, novel chaotic developed simple design by introducing obstruction-pairs on bottom microchannel. An obstruction-pair, which composed two hexahedron blocks arranged an asymmetric manner, can induce rotational flow along down-channel direction due to anisotropy resistance. By utilizing characteristic four...
Abstract Three‐dimensional serpentine micromixer (TSM) has been well known to be an attractive design because of its simple fabrication and efficient mixing performance, but basic characteristics have not fully investigated notwithstanding several reports in the past. The present article comprehensively investigates flow TSM. Three major mechanisms are identified, namely rotation, lamination, chaotic advection. performance TSM is analyzed compared terms three by means numerical analysis with...
We review the fundamental modeling and numerical simulation for a prediction of fiber orientation during injection molding process polymer composite. In general, involves coupled analysis flow, temperature, moving free surface, kinematics. For governing equation Hele‐Shaw flow model along with generalized Newtonian constitutive has been widely used. The kinematics group fibers is described in terms second‐order tensor. Folgar‐Tucker recent models such as slow are discussed. Also various...
This article presents heat transfer characteristics of circular and elliptic cylinders in cross flow for various Reynolds numbers. Numerical investigations as well wind tunnel experiments are carried out to study the convective in-line cylinder banks. In particular, upstream downstream compared terms local average Nusselt The effects turbulence induced by on discussed with help detailed numerical results.
In this study, large-scale production of microalgal lipid containing high levels docosahexaenoic acid (DHA) by fermentation Aurantiochytrium sp. KRS101 was performed. The strain yielded productivity docosahex-aenoic 1.08 and 1.6 g/L/d at 300-L 5000-L scale stirrer-type bioreactor. significantly enhanced upto 5.6 6000-L airlift-type bioreactor, probably due to the reduced shearing force. could be efficiently recovered safe extraction methods such as ethanol extraction, hot water or...
