Research Abstract

In this research organization, research on the real phenomenon reproducibility by using the unsteady CFD analysis technique was done for the purpose of the application to the next-generation environmental design of the analysis technique for air flow and thermal environment. Before dealing with an unsteady phenomenon, accuracy of CFD analysis was mainly verified in 2003. The accuracy of CFD analysis was verified following the preceding year, and the LES database was created based on the examination result in 2004. In 2005, experiment and survey for the unsteady air-conditioning interior of a room were performed, and accuracy verification and practical use possibility of the analysis technique of air-flow were examined. The result outline acquired by this research is shown below.
・In examination of the prediction technique of the analysis by LES, CFD analysis by LES and k-e was carried out for non isothermal indoor air-flow in which the buoyancy effect excelled, and the validity and the predominancy of LES were checked. Consequently, LES showed that it was the practical prediction technique also on the business level.
・While performing ventilation performance evaluation of the inflow opening based on a local similarity model, the wind tunnel experiment was conducted about the opening of various forms for the purpose of creating the design data for calculation of the amount of ventilation, and the ventilation performance database was created.
・the environment resulting from regular design and that resulting from movable-nozzle design were compared using LES. ADPI, an indicator of the conditions in the occupied zone during air conditioning, was calculated, and confirmed the effectiveness of air conditioning using movable nozzle outlets.
・The building circumference wind pressure distribution by the improvement k-e model which introduced limiter proposed by Durbin was predicted, and optimization of the model parameter based on comparison with an experiment was reported.
