Tech., Xi′an 710055, China) Abstract: The columns are widely distributed within the architectural space. In order to effectively use them, a novel ventilation mode named square column attached displacement is presented, which can help improve ventilation efficiency and create comfortable indoor environment. The velocity and temperature fields under different supply air velocities and temperatures are studied by numerical simulation using RSM-IP turbulence model. In addition, the effect of square column width, column span and air outlet location on airflow patterns also is researched, respectively. The current results show the square column attached displacement ventilation model has the advantages of both mixing and displacement ventilation systems. In general, under the reasonable parameter settings of supply air velocity and temperature, this ventilation mode can be used in HVAC sys
