Research Abstract

New Method for a numerical analysis of the air movement in and/or around buildings was developed in this project. The airflows in and around building, are very complicated. In order to predict the flow properties of such a complicated flowfield, a lot of researches has been carried out. The flow modellings used in the previous researches can be classified into two types, namely,
a) models focused on the macroscopic features of the airflow in the whole building airflow systems, using single (or multi) zone theory which is based on the assumption that zones are well mixed.
b) models focused on the detailed microscopic features of the airflow in small portions of building systems (e.g., single rooms) using numerical solutions to the microscopic equations of fluid motion (e.g., Navier-Stokes equations). In this project, a new method which integrates the macroscopic and microscopic approaches was developed. The high practicability of the method was confirmed by analyzing two types of flowfields, ie., the airflow in and around a building with open windows and the airflow in the whole building airflow systems.
