We analyzed the ventilation characteristics of revolving doors, which are movable boundaries.
What are the ventilation characteristics of revolving doors? In revolving doors, where the opening area changes significantly over time, it is important to capture the temporal variation of the ventilation airflow. This analysis treats the revolving section as a moving object, aiming to gain insights into the circulation of air inside and outside. For more details, please download the catalog.

basic information
【Analysis Model and Conditions】 - Diameter of the rotating section: 4m, Height: 3m - Total number of grids: 113×108×49 = 597,966 - Rotation speed of the rotating section: 3 times per minute - Temperature assumed for winter: Internal 22°C, External 0°C - In this analysis, wall heat transfer and external wind are not considered, but it is possible to take them into account - It is also possible to change the shape of the door or to vary the rotation speed 【Analysis Results】 - The wind speed distribution around the rotating door during operation is displayed in a diagram → Over time, the internal and external air is drawn into the rotating door and released on the opposite side - The movement of airflow becomes intense due to the interaction of air with different temperatures, causing mutual replacement ● For more details, please contact us or download the catalog.
