| Outline of Final Research Achievements |
The purpose of this study is to establish a design method to create a high level of IAQ. We proposed a concept of Net Escape Velocity (NEV), as a new index for ventilation effectiveness in an indoor environment and to establish a design method of indoor environment based on NEV. NEV represents the effective velocity at which the contaminant is transported/diluted from a target point. The possibility of NEV as an index for evaluating the structure of a non-uniform concentration field of a contaminant was revealed.
In addition, a purpose of this research is to establish of numerical prediction of concentration reduction performance of VOCs in Indoors by photocatalytic oxidation (PCO). The kinetic studies were carried out for PCO of toluene as a VOCs in the gas phase over TiO2-bound building materials using a 20 L test chamber developed by us and CFD simulations were performed using the same boundary conditions as the experiments to identify model parameters of the PCO process.
