We analyzed the ventilation characteristics of the sliding door, which is a movable boundary.
What are the ventilation characteristics around the windbreak room of the sliding door? In sliding doors that open and close based on traffic volume, it is important to capture the temporal changes in ventilation airflow. This analysis treats the sliding part as a moving object and aims to gain insights into the circulation of air inside and outside. For more details, please download the catalog.

basic information
【Analysis Model and Conditions】 - The model consists of four sliding sections, each 1m long and 3m high, and a vestibule measuring 2m x 2m. - The total number of grids is 110 x 49 x 830 = 830,060. - The sliding sections move at a speed of 1m/s, with an alternating opening and closing frequency of 2 times. - The temperature is set for winter conditions, with an internal temperature of 22°C and an external temperature of 0°C. - This analysis does not consider wall heat transfer and external wind, but it is possible to include them. - Changes to the door shape and variable movement speeds are also possible. 【Analysis Results】 - The temperature distribution and velocity vector diagram around the sliding door during operation are illustrated. → Over time, the internal and external air is drawn into the vestibule, showing the state of air intrusion into the room. - The movement of the airflow becomes more intense as air with different temperatures comes into contact and replaces each other. → The amount of air exchanged varies significantly due to the temperature difference. ● For more details, please contact us or download the catalog.

Company information
In environmental simulation, we are engaged in the independent development and sale of a three-dimensional fluid analysis program, as well as contract analysis services using this software. For over a decade, we have been involved in thermal fluid analysis in fields such as architecture, civil engineering, machinery, and electronics, handling numerous analyses and accumulating a wealth of know-how and knowledge. Our diverse analysis and visualization functions, honed through practical experience, have received high praise as CFD software from many companies and research institutions. ● Import function for BIM-compatible CAD data such as Revit and DXF ● Import function for geographic information system (GIS) data ● SuperCartesian function that freely represents diagonal boundaries and complex curved surfaces ● High-speed, high-precision radiation calculations and high-precision turbulence analysis using DNS ● Moving boundary problem analysis function that accommodates the movement of multiple objects in space ● User-friendly interface and easy-to-understand animation features Of course, we also provide software support and accept contract analyses. Focusing on air conditioning ventilation and wind environment analysis, we offer high cost-performance solutions for a wide range of problems, from simple and small-scale issues to complex and large-scale analyses. We look forward to your visit, along with our extensive analysis case studies.
