By artfully applying different potentials to different electrode pairs, Lorentz-force with different sizes can be created, driving the liquids in a desired direction for pumping, and inducing fluid circulation at a cross-section for mixing. The results show that the micro-mixer proposed in this study can achieve high mixing performance for electrolytes, together with differential pumping capabilities for the two different miscible fluids. The effect of the total difference in potential applied to the electrodes in pumping section on the mixing performance is numerically analyzed.

Xuejiao Xiao,Shangjing Yang,김창녕 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.9
In this study, numerically analyzed is the effect of the orientation of the applied transverse magnetic field on the mass-imbalance of MHD flows in a multi-channel conduit consisting of three parallel channels with spatially non-uniform electric conductivity, by using CFX. In the multi-channel conduit, co-flows are driven by the constant pressure gradient in the three channels so that the mass-imbalance among the three channels may be observed in the above situations. Here, the mechanism leading to the mass flow imbalance caused by the orientation of magnetic field and by the spatial difference in the electric conductivity is discussed specifically. The results show that when the channels have spatially different electric conductivity the mass flow imbalance becomes more significant with an increasing of the angle of the applied magnetic field with respect to the plane parallel to the three channels (α).

Numerical analysis of an MHD micro-device with simultaneous mixing and pumping capability
Xuejiao Xiao,김창녕 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.38 No.-
In this study, a new magneto-hydrodynamic (MHD) micro-device with simultaneous mixing andpumping capability is proposed, and a numerical investigation for the performance of the device isperformed. The present MHD micro-device utilizes the arrays of electrodes deposited on duct walls. Byjudiciously applying different potentials to different electrode pairs, the Lorentz-force can be created,directing the liquid to move in a desired path for pumping without a need of separate pumps, andsimultaneously inducing complex flows for mixing. The results show that the micro-device proposed inthis study can achieve highly-efficient, simultaneous mixing and pumping for electrolytes.

Effect of Thermal Treatment on the Texture and Microstructure of Abalone Muscle (Haliotis discus)
Beiwei Zhu,Xiuping Dong,Liming Sun,Guihua Xiao,Xuejiao Chen,Yoshiyuki Murata,Chenxu Yu 한국식품과학회 2011 Food Science and Biotechnology Vol.20 No.6
The texture and microstructure of edible abalone meats were studied during heat treatments from 50to 100^oC for 60 min. No increase in extractable soluble collagen content was observed below 80^oC, but a 9-fold increase was observed at 100^oC. SDS-PAGE showed that extractable myosin heavy chains and paramyosin contents reduced significantly at 80^oC, and disappeared completely at 100^oC. The shear force increased slowly from 50 to 70^oC, but relaxed back to the initial level at 100^oC. Rapid reduction of hardness was observed at 50^oC, minimum hardness was obtained at 100^oC. Springness, cohesiveness,chewiness, and resilience were enhanced to maximum levels at 70, 90, 70, and 90^oC, respectively. Optical micrographs and transmission electron microscope showed a significant increase of intermyofibrillar gaps at 90^oC and broken fibers at 100^oC. Results suggested that 80^oC might be a suitable temperature to produce ready-to-eat abalone products.
