  • control of minimum film boiling quench temperature of small spheres with micro structured surface
    International Journal of Multiphase Flow, 2018
    Co-Authors: Kang Junyoung, Kiyofumi Moriyama, Lee Gi Cheol, Massoud Kaviany, Kim Moo Hwan
    Abstract:

    Abstract The control of minimum film-boiling quench temperature, TMFB is investigated in water quenching experiments with several micro-structured surfaces on small spheres (Diameters 10 and 15 mm) under saturation temperature Tsat and 1 atm. The results show increase in TMFB and is related to the temperature drop across the micro-structures, and affected by its effective thermal conductivity 〈k〉, height L, and Base Diameter D, Based on the fin theory. The local temperature drop of surface microstructure depends on the hybrid Biot number, B i h = h L 2 / ( 〈 k 〉 D ) , where h is the heat transfer coefficient. The liquid–solid contact depends on this microstructure-tip temperature, and a model for TMFB with synthetic surface micro-structure is proposed and compared with the experimental results. The theoretical limit of maximum TMFB (under saturated water at 1 atm) for surface micro-structured small sphere is reached when Bih is beyond 102.

  • minimum film boiling quench temperature increase by cuo porous microstructure coating
    Applied Physics Letters, 2017
    Co-Authors: Jun Young Kang, Massoud Kaviany, Hyun Sun Park, Kiyofumi Moriyama
    Abstract:

    Increase in the minimum film-boiling quench temperature, TMFB, is achieved with microstructured CuO particles, and attributed to local cooling (fin effect) by the microstructure causing liquid–solid contact. A periodic structure is obtained using electrochemical deposition of 1 μm Diameter particles on brass sphere Diameter 15 mm forming unit-cell porous cones of average height L = 100 μm and Base Diameter D = 20 μm. Fin analysis predicts the cone tip cooling to the homogeneous nucleation temperature of water (∼330 °C), while the Base temperature is at 600 °C. This causes liquid–solid contact during quenching, and analysis suggests the fin effective thermal conductivity ⟨k⟩ and fin characteristic length L2/D are key to this liquid–solid contact that influences TMFB.

  • The Influence of the Appendiceal Base Diameter on Appendix Stump Closure in Laparoscopic Appendectomy
    World Journal of Surgery, 2016
    Co-Authors: Samir Delibegović, Zlatan Mehmedović
    Abstract:

    Background Closure of the appendiceal stump is the most critical part of laparoscopic appendectomy. Establishing the average Diameter of the inflamed appendix, and forming the appropriate size of clip, endoloop or stapler length, would make this critical phase of laparoscopic appendectomy easier. Methods One hundred and fifty consecutive patients, with the diagnosis of acute appendicitis, were included in this study and divided into three groups according to the histological verification of the status of the infection, as follows: phlegmonous, gangrenous and perforated forms of acute appendicitis. The external Diameter of the appendiceal Base was measured, and the widest part of the appendix with the mesoappendix and the tip, with the help of Vernier callipers, and the measurement was expressed in millimetres. Results The average size of the appendiceal Base in the phlegmonous form was 10.29 ± 3.13, in the gangrenous form 12.41 ± 3.56, and in the perforated form 12.42 ± 3.64. The maximal size of Base was observed in the perforated form, 23.13 mm. The dimensions of the appendiceal Base, the central part and the tip in the phlegmonous form were statistically significantly smaller than in the gangrenous and perforated forms of acute appendicitis. The size of the appendix did not differ statistically significantly in the gangrenous and perforated forms of acute appendicitis. Conclusion In view of the price, the size of the opening, radiological advantage and biocompatibility, the Hem-o-lok clip is the most effective, although its internal Diameter should be increased. The DS clip is also effective, but the size of the opening sometimes makes application difficult, and possibly increasing the length of the legs and the opening would make this clip ideal. Staplers have the best characteristics, but their price means they are an option only for forms where it is not possible to close the stump using other methods.
