Abstract

This study examines the variance of wind impacts on low-rise gable-roofed buildings that do not have any open faces to the wind domain over distinct interference situations. In full blockage arrangements, this is achieved by adjusting the spacing between the buildings. Because there are no specifications in wind standards for building structures of this kind, computational simulations are carried out using the fluid flow simulator of ANSYS CFX software using the Standard k − ε model. These kinds of research necessitate the use of either a real wind tunnel environment to measure the pressure or a virtual computational fluid dynamics (CFD) simulation of the wind environment. In this work, CFD simulations were performed for a total of four distinct spacing circumstances and four varied increasing wind incidence angles of 0°, 30°, 60°, and 90° to get the coefficient of pressure (Cp). The results have been showed with the help of contours on the roofs of structures, pressure coefficient (Cp) and velocity streamlines for different cases. Minimum value of Cp was found in 1.5b spacing configuration with wind incidence angle 60° and maximum value of Cp in 2b spacing configuration with wind incidence angle 60° (here b = width of structure).
