碩士 / 中國文化大學 / 建築及都市設計學系 / 105 / In recent years, global warming has intensified environmental and climatic changes. Thus, reducing energy consumption and creating architectural design concepts adaptive to the environment have become mainstream. Taiwan has green building policies that encourage improvement in the efficiency of resources used and a reduction in ill effects on the environment and human health. According to relevant studies, a well-ventilated street canyon with favorable wind field can improve environmental thermal comfort levels and reduce regional air pollution. Although numerous studies have been conducted on wind fields in urban environments, few have focused on the environment of coastal industrial parks, where the wind is very strong, thus making it necessary to maintain a high-quality wind environment. This study examined building layout norms for the wind field at the coastal industrial park. The theories used in the study included computational fluid dynamics (CFD), thermal comfort, and dimensionless analysis. CFD is the control equation that uses numerical methods to obtain the fluid mechanics; it can predict the movement of the flow field through different boundary conditions. Thermal comfort theory explains the thermal equilibrium of the human body through four physical environment factors (temperature, radiation, wind speed, and humidity) and the two human factors (activity, clothes). Dimensionless analysis examines the relationship between physical quantities; in this study, it was used to examine the relationship between atmospheric climate and microclimate. Relevant literature was inductively analyzed; basic data were collected through actual measurement, and Fluent software was used to analyze the base outdoor physical environment through numerical simulation and to measure thermal comfort. Actual and CFD simulated data were compared and validated to enhance the trustworthiness of the CFD simulated data. Variables were adjusted according to the CFD model of varying conditions, and dimensionless analysis was used to present the relationships between the data; finally, an urban design principle for the optimal wind field was selected based on the analysis results. The research results showed that the best height:width ratio of street canyons was 0.1–0.3, a single-opening layout was preferred for superior thermal comfort, and the staggered method of pollution dispersion was the most effective.
