A Bibliographic Survey of Number of Cells Needed in CFD Analysis of Room Air Flow

This study prepares a list of articles on the CFD analyses of room air flow in the architecture field in Japan, and compiles information related to CFD analysis conditions described in each article. The discussion addresses trends in analytical conditions in Japan, the yearly transition of the number of cells, usefulness of the estimate formula for the number of cells of VDI 6019, and a rough guideline for number of cells for a low Reynolds Number model.
