  • Experimental study on modeled caudal fins propelling by elastic deformation

    Baba N., Obi S.

    American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FEDSM (American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FEDSM)  1 2018

    ISSN  9780791851555

     View Summary

    Copyright © 2018 ASME. The present study proposes a new device for the experiment of self-propelling bodies in the water. As opposed to the studies in the past whose experiments were often carried out in a water channel with a given freestream velocity, the new device allows the model to swim under an actual self-propelling condition. The adopted model mimics the caudal fin of various shapes and made of elastic material, and the self-propelling speed is investigated primarily as a function of the forcing frequency. The influence of the amplitude of forced vibration and the materials of different elasticity is also investigated. The flow field around the model fin has been measured by PIV to characterize the flow pattern produced by the fin-motion.

  • Experimental and computational fluid dynamic analysis of laboratory-scaled counter-rotating cross-flow turbines in marine environment

    Doan M., Alayeto I., Padricelli C., Obi S., Totsuka Y.

    American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FEDSM (American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FEDSM)  2 2018

    ISSN  9780791851562

     View Summary

    Copyright © 2018 ASME Power generation of laboratory-scaled marine hydrokinetic (MHK) cross-flow (vertical axis) turbines in counter-rotating configurations was scrutinized both experimentally and numerically. A tabletop experiment, designed around a magnetic hysteresis brake as the speed controller and a Hall-effect sensor as the speed transducer was built to measure the rotor rotational speed and the hydrodynamic torque generated by the turbine blades. A couple of counter-rotating straight-three-bladed vertical-axis turbines were linked through a transmission of spur gears and timing pulleys/belt and coupled to the electronic instrumentation via flexible shaft couplers. A total of 6 experiments in 3 configurations, with various relative distances and phase angles, were conducted in the water channel facility (3.5 m long, 0.30 m wide, and 0.15 m deep) at rotor diameter base Reynolds number of 20,000. The power curve of the counter-rotating turbines (0.068-m rotor diameter) was measured and compared with that of a single turbine of the same size. Experimental results show the tendency of power production enhancement of different counter-rotating configurations. Additionally, the two-dimensional (2D) turbine wakes and blade hydrodynamic interactions were simulated by the shear stress transport k-omega (SST k-omega) model using OpenFOAM. The computational domain included a stationary region and two rotating regions (for the case of counter-rotating turbines) set at constant angular velocities. The interface between the rotating and stationary region was modeled as separated surface boundaries sliding on each other. Velocity, pressure, turbulent kinetic energy, eddy viscosity, and specific dissipation rate field were interpolated between these boundaries.

  • Development of a Mechanical Engineering Test Item Bank to promote learning outcomes-based education in Japanese and Indonesian higher education institutions

    Jeffrey S. Cross, Estiyanti Ekawati, Satoko Fukahori, Shinnosuke Obi, Yugo Saito, Nathanael P. Tandian, and Farid Triawan

    Tuning Journal for Higher Education (University of Deusto)  5 ( 1 ) 41 - 73 2017.11

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  2340-8170

     View Summary

    Following on the 2008-2012 OECD Assessment of Higher Education Learning Outcomes (AHELO) feasibility study of civil engineering, in Japan a mechanical engineering learning outcomes assessment working group was established within the National Institute of Education Research (NIER), which became the Tuning National Center for Japan. The purpose of the project is to develop among engineering faculty members, common understandings of engineering learning outcomes, through the collaborative process of test item development, scoring, and sharing of results. By substantiating abstract level learning outcomes into concrete level learning outcomes that are attainable and assessable, and through measuring and comparing the students’ achievement of learning outcomes, it is anticipated that faculty members will be able to draw practical implications for educational improvement at the program and course levels. The development of a mechanical engineering test item bank began with testscale test implementation in 2016 of 348 first semester master’s students in 9
    institutions in Japan, using both multiple choice questions designed to measure the
    mastery of basic and engineering sciences, and a constructive response task designed
    to measure “how well students can think like an engineer.” The same set of test items
    were translated from Japanese into to English and Indonesian, and used to measure
    achievement of learning outcomes at Indonesia’s Institut Teknologi Bandung (ITB)
    on 37 rising fourth year undergraduate students. This paper highlights how learning
    outcomes assessment can effectively facilitate learning outcomes-based education, by
    documenting the experience of Japanese and Indonesian mechanical engineering
    faculty members engaged in the NIER Test Item Bank project.

  • A smooth partition of unity finite element method for vortex particle regularization

    KIRCHHART MATTHIAS, OBI SHINNOSUKE

    SIAM Journal of Scientific Computing 39 ( 5 ) A2345 - A2364 2017.10

    Research paper (scientific journal), Joint Work, Accepted

     View Summary

    We present a new class of C∞-smooth finite element spaces on Cartesian grids, based on a partition of unity approach. We use these spaces to construct smooth approximations of particle fields, i.e., finite sums of weighted Dirac deltas. In order to use the spaces on general domains, we propose a fictitious domain formulation, together with a new high-order accurate stabilization. Stability, convergence, and conservation properties of the scheme are established. Numerical experiments confirm the analysis and show that the Cartesian grid-size should be taken proportional to the square-root of the particle spacing h, resulting in significant speed-ups in vortex methods.

  • A Splitting-free Vorticity Redistribution Method

    KIRCHHART MATTHIAS, OBI SHINNOSUKE

    Journal of Computational Physics (Elsevier)  330   282 - 295 2017.02

    Research paper (scientific journal), Joint Work,  ISSN  0021--9991

     View Summary

    We present a splitting-free variant of the vorticity redistribution method. Spatial consis-tency and stability when combined with a time-stepping scheme are proven. We propose a new strategy preventing excessive growth in the number of particles while retaining the order of consistency. The novel concept of small neighbourhoods significantly reduces the method’s computational cost. In numerical experiments the method showed second order convergence, one order higher than predicted by the analysis. Compared to the fast multipole code used in the velocity computation, the method is about three times faster.
