In the previous paper, measurements were carried out in a test room in which a complex ceiling air diffuser was installed, and coarse arid CFD was conducted using the Box method (P. V. Nielsen et al.; 1978, 1992) and the Prescribed Velocity Method (P. V. Nielsen et al; 1980) based on the boundary airflow data obtained by the experiment. The results of the CFD using these methods showed good agreement with the measured value. In this paper, CFD simulation using the unstructured fine elements system was applied to obtained airflow data around a air diffuser as boundary conditions of coarse grid CFD. The unstructured CFD simulation reproduced the measured airflow distribution in the room and gave the boundary conditions for complex air diffuser with much less effort than by the experiment. It was also confirmed that coarse grid CFD using P. V Method with boundary airflow data obtained by the unstructured CFD gave good results.
