     View Summary

    <p> Personal air conditioning system is an air distribution method to provide a satisfactory thermal environment. The purpose of this study is to propose a CFD modeling method of the airflow from personal air supply terminal. As the first step, a full-scale experiment was conducted under the isothermal condition, where a personal air supply terminal was installed on the ceiling. The supply airflow rate was regulated at 28 m<sup>3</sup>/h. In the experiment, 2-D velocity was measured using a X-type hot-wire probe, and turbulent statistics were measured using an I-type hot-wire probe. The experiment was conducted to obtain boundary conditions for CFD and to obtain true value for accuracy verification. Second, CFD analyses using Standard <i>k-ε</i> Model (SKE), SST <i>k-ω</i> Model (SST) and Reynolds Stress Model (RSM) were performed, and SKE and SST showed good agreement with experimental result as shown in Fig. 9. To perform this Detailed CFD analysis, a large number of grids is required, which leads to large computational load and difficulty in analysing a large space. Therefore, to decrease the number of grids without loosing accuracy, two CFD modeling methods were applied in this paper, i.e., momentum method and P.V. method. The analysis using these two methods was performed, and the accuracy was verified by comparing the result with that of above-mentioned detailed analysis. As the result, in the case of 50mm-mesh, the decrease of the accuracy was not significant because the number of grids is relatively large. On the other hand, in the case of 100mm-mesh, the accuracy was greatly decreased if no modeling method was applied. However, the accuracy was obviously improved by using the momentum method and P.V. method as shown in Fig. 12 and 13.</p><p> </p><p> The conclusions obtained in this paper are summarized as follows.</p><p> (1) In the accuracy verification where the experiment was compared with CFD, both SKE and SST showed good agreement with the experimental result regarding average 2-D velocity distribution on the central section. However, RSM overestimated the diffusion of momentum, and consequently showed the tendency to underestimate the reach of air flow compared to the experimental value.</p><p> (2) In the CFD analysis using the Momentum method, the accuracy is not sufficient if compared to the detailed analysis. However, the tendency of the velocity distribution was quite similar to that of the detailed analysis. In the case of a 100-mm mesh, the improvement of accuracy by CFD modeling becomes large if compared to the case of 50-mm mesh.</p><p> (3) It was confirmed that the P.V. method had better accuracy of velocity distribution if compared to the momentum method, and that the reaching distance of 0.5 m/s was well agreed with the detailed analysis in the case of diagonal supply.</p><p> </p><p> As a future prospect, CFD analysis for a large office space where a large number of personal air terminals are installed is to be conducted to study the influence of each air flow of personal airflow and the influence on ambient air flow.</p>

  • Effective Turf Planting Layouts for Heat Mitigation in School yards

    Noriko Umemiya, Takeshi Kishimoto, Tomohiro Kobayashi

    Building Simulation 2019  2019.09  [Refereed]

     View Summary

    Using CFD simulation, this study compared heat mitigation effects of partial turf planting in school yards and of overall turf planting. Typical school lots and surrounding buildings were modelled according to actual conditions. Temperature contour lines and air flow vectors on school yards showed that heat mitigation effects are dependent on wind speed and direction. The wet bulb globe temperatures were evaluated and compared. Turf planting in western parts of the school yards was most effective. Heat mitigation at leeward wind areas was slight.

  • A comparison between elderlypeople and young people in factors related to gazing characteristics during walking in corridors

    Mika Tomita, Noriko Umemiya, Yasuha Kureyama

    Proceedings of the 12th Asia Lighting Conference    193 - 200 2019.08  [Refereed]

     View Summary

    By measuring gazing points of elderly people (65–91) and young people (21–25) as they walked down corridors, this study examined gazing characteristics and their mutual relations, along with physical strength and two-step size.
    Results clarified the following five points.
    1) Among these participants, 64.1% of elderly people and 21.4% of young people had equal to or less than 1.3 two-step size. People with equal to or less than 1.3 two-step size have a higher probability of falling.
    2) The frequency distribution of gazing points revealed four groups: G1) 1 area concentration, G2) 2 area concentration, G3) 3 or 4 area concentration, and G4) more than 5 area distribution.
    3) The two-step size was worst in G2 and greatest in G3 for elderly people. Therefore, people in G2 tend to fall, but those in G3 do not. Age is unrelated to these results.
    4) Gazing characteristics are unrelated to the ease of falling for young people.
    5) In G2 of elderly people, someone who is more impervious to glare has a smaller two-step size.

  • Pupil size change and light evaluation of elderly people

    Noriko Umemiya, Yasuha Kureyama and Mika Tomita

    Proceedings of the 12th Asia Lighting Conference    510 - 515 2019.08  [Refereed]

     View Summary

    This study measured pupil size and forehead illuminance simultaneously for elderly people 65 years or older and young university students during corridor walking in daily lighting. Subjective evaluation of the light environment in an experimental room was done for dark and light conditions. Brightness, glare, uniformity, flickering, lighting comfort, lighting preference, and performance were evaluated. Illuminance was 550 lux in the dark condition and 3300 lux in the light condition. For the elderly and young people, pupil size response to illuminance and the relation of its change to forehead illuminance during walking and subjective light evaluation to dark and light conditions in the experimental room were compared. The gradient of pupil size to forehead illuminance was used as an index of the response. Results show differences in gradients between elderly and young people in lighting preference evaluation of the dark condition and in performance evaluation of the light condition.
