A Numerical Experiment on the Effect of Stone Fences on the Wind Stream Formation in Vernacular Architecture of Jeju

Abstract

Purpose: A three-building thatched residence with stone fences representing the traditional housing architecture in Jeju has been studied with the help of simulation tools. The main goal of this study was to identify the role of stone fences on the overall wind flow through the three building structures. Especially, the physical dimensions of the fence (height, size and, the number of holes) along with its distance away from the building wall (façade) have been extensively studied concerning its effect on the formation of wind streams as the flow develops interacting with its surroundings (building elements, ground, etc.). Method: Stone fences installed along the periphery of a traditional residence (comprised of three buildings each with a thatched roof) can significantly influence the passage of wind through its internal region. Various cases have been explored while changing the key parameters influencing wind flows, such as height and holes of fences. Result: The results provide clear evidence that holes in stone fences provides a more uniform path for the wind flow as compared to a fence without any holes. Moreover, the wind speed can be greatly influenced by the change in fence height and the presence of holes in it.
