This paper presents a numerical method aiming at recreating the concentration field of a pollutant at each point of a ventilated enclosure that contains one or several pollutant sources of unknown emission rate.
This paper deals with a 3D numerical study to assess the effectiveness of a displacement ventilation system to remove particulate pollutants, generated in the occupied zone of a room.
In this study, an office with mixing ventilation is considered. The CFD analyses show that for high cooling loads it is useful to couple a cold ceiling to primary air system
This paper deals with the integration of CFD analysis tool with genetic algorithms. This integrated process presents advantages in generating design alternatives that tally with multiple design, thermal and ventilation criteria.
This paper deals with a CFD simulation of a chilled ceiling in a test chamber. The results demonstrate that a slight non-uniformity in cooling power of the ceiling panels produces a great asymmetry in predicted room airflows.
The aim of this work was to develop a new calculation method of the zonal air velocity in ventilated room during the design stage. The verification showed a good correlation between the method and the experimental data.
In this paper the application of CFD simulation with unstructured fine elements system was carried out to obtain airflow data for the boundary conditions for an air flow.Tthe results were compared with the measured data.
In this paper, 2D - CFD calculations of the flow are carried out . Two different turbulence models were employed and the results compared. The differences between experiments and calculations are explained by introducing a topological apparatus
To simulate non-isothermal indoor airflow more quickly and correctly, a turbulence model is performed in STACH-3, the 3-D CFD code developed by Tsinghua University. Validation reveals that it is satisfied for non-isothermal indoor airflow. The air distribution in an actual conference room with VAV system is numerically solved by CFD method, and the conventional jet theory method is used for a comparison of the results. Subsequently an analysis is done of the cold air draught and hot air climbing problems.
