A natural ventilation analysis of building clusters under external wind conditions was conducted.
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 thermal environment analysis technology through numerical calculations have made it possible to perform analyses with over a million meshes even on personal computer-based systems, 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】 - In the rear of the parking structure located upwind, external wind is significantly attenuated. - Some ventilation is expected inside the existing structures on the downwind side of the parking structure. - The newly constructed building located furthest downwind has the highest eaves height. - It directly receives external wind from above. - Analysis combined with air conditioning analysis is also possible.
