We conducted a natural ventilation analysis of building clusters in the presence of external wind.
The ventilation analysis of wholesale markets involved the natural ventilation analysis of building complexes in the presence of external winds. In recent years, advancements in numerical computation techniques for thermal environment analysis have made it possible to conduct analyses with over a million meshes even on personal computer bases, allowing for detailed construction of building structures. If the detailed structure of the building can be represented, it becomes possible to directly evaluate the state of wind circulation by simultaneously solving the thermal and flow fields of the internal and external spaces.

basic information
【Analysis Model】 - In order to secure the specified thermal environment, it is possible to actively utilize not only air conditioning equipment but also natural ventilation. - An external velocity field is set, and internal heat loads such as equipment heat generation and through-flow loads are also considered. - The number of grids for analysis is 194×130×41=1,034,020, exceeding one million meshes, but it can be analyzed on a personal computer. - The grids are finer in each building to represent its structure. - The power law of external wind is applied for the settings. 【Analysis Results】 - External wind significantly attenuates behind the parking structure located upwind. - Some ventilation is expected inside the existing structures on the downstream side of the parking structure. - The newly constructed building, located most downwind, has the highest eaves height. - It directly receives external wind from above. - Analysis combined with air conditioning analysis is also possible. ● For more details, please contact us or download the catalog.
