Macroscopic analysis of heat and airflow transport within atrium by means of numerical simulation.

The macroscopic behaviour of heat and airflow transport within an atrium is analyzed based on the result of a microscopic numerical stimulation. The result of the numerical simulation agreed fairly well with that of the model experiment. In orde

The role of infiltration for indoor air quality

Multifamily buildings with natural ventilation are still being built and exploited. Such buildings are often equipped with individual gas-fired water heaters located in windowless bathrooms. It implicates the possibilities of improper gas exhaust as a result of the decrease of infiltration, what could be sometimes even harmful for the occupants' health. Based on the numerical simulations, analysis of ventilating air flows in typicalmultifamily dwelling house will be carried out.

Application of mathematical modelling to the evaluation of building ventilation systems.

Numerical modelling is performed for three-dimensional turbulent buoyant flows emerging from an air diffuser in an air-conditioned, ventilated room. The velocity and temperature distributions of air in the room are calculated, and the calculated results are found to be in reasonable agreement with published experimental observations. Calculations of Air Diffusion Performance Index (ADPI) for a sidewall grille are carried out for different flow rates of air supply. The predicted ADPI values are found generally to be consistent with the corresponding experimental values.
