| Research Abstract |
In this report, as the first step, transfer model of heat and moisture for horizontal running water was indicated according to balance of heat and moisture measured in the laboratory. At the second step, CFD (computer fluid dynamics) which was built with transfer model of heat and moisture was compared with actual results as a numerical verification. We need to measure actually distribution of air velocity for adjacent boundary layer on the running water surface for explaining a transfer mechanism of heat and moisture. Such distributions of air velocity on the running water surface were measured by using PIV.
It is necessary to estimate by using numerical simulations before planning thermal-aero environment of indoor open spaces. At the third step, improved effects were evaluated by using numerical simulations for planning future thermal-aero environment of indoor open spaces.
To design thermal-aero environment for inner open spaces, we need to know the relationship between illuminate environment and solar radiation trough the glass roofs for such spaces. It is possible to estimate thermal load for void spaces of top light type. Classification of atrium spaces was done like side-core model, center core model and linear core model. Best option was indicated from the parameter analysis of PIV.
To discuss the numerical analysis by using macro-model that needs for planning of thermal-aero environment to use weak temperature distribution in inner open spaces should be continued. Also CFD analysis used cool running water surface should be continued.
