Computational fluid dynamics analysis for thermal-wind environment simulation of urban street in Hanoi city
Introduction. One of the most important tasks in architecture and urban planning is to create the most optimal, comfortable and safe environment for human's live, work and leisure. This issue cannot be solved without taking into account the environment factor such as temperature and wind in a city. Modeling of the urban thermal-wind regime has been carried out to assess the temperature and air speed of the city streets of Hanoi. Materials and methods. Computational Fluid Dynamics (CFD) uses numerical methods to solve fluid mechanics equations by using a computer model to predict flow fields. In this study, author has used ANSYS 19.1 of the FLUENT software package to conduct the model analysis of urban street thermal environments. The study conducted a series of experimental procedures in urban street alleys that were oriented towards placement in the urban area of Trung Hoa Nhan Chinh in the Thanh Xuan district, Hanoi cit. Results. The highest temperatures were observed around the southeast side of the buildings in the urban area of Trung Hoa Nhan Chinh. Thus, a decrease in building density and maintaining the distance between buildings will contribute to the movement of the wind to cool city streets. Conclusions. The greatest contribution to the work has been created by using a micro-weather station. Analysis of the assessment of the surrounding buildings, landscaping, shade and human activities can recommend measurable improvement the thermal comfort of the streets.
