Scaling Model Similarity Theory and Its Application in Large Space Building Indoor Thermal Environment Research

With the acceleration of urbanization, large space building, as one of the most important spatial organization forms of urban buildings, its thermal comfort and energy saving have become the focus of current attention. The air flow process in large space buildings is complex and the thermal environment is uneven. The field measurement research is affected by many complex factors. Therefore, the indoor thermal environment research of large space buildings usually needs to be combined with other methods except field measurement. In this paper, the similarity theory of scale model is introduced, and the combined experiments of scale model, numerical simulation and other prediction methods are summarized, which provides a new idea for the measurement and research of indoor thermal environment in the cold and dry areas of Northwest China in the future.
