Wind is an omnipresent natural element with which the structures must be in harmony during normal winds and also gusts. Civil engineering structures are stationary with respect to the ground. However, they are moving bodies with respect to the air. Thus, it becomes imperative for civil engineers to obtain wind pressure acting on a structure at various points of interest which has to be incorporated in the structural design. For simple geometry, one could infer the values offered in the respective national standards. However, for complex geometry one must resort to obtaining the values using open/closed circuit low speed wind tunnels. This study presents the dimensioning principles involved in an open circuit low speed wind tunnel and the bluff body to be introduced, various possible configurations of an open circuit low speed wind tunnel based on parametric study and an analysis performed using Ansys®—Fluent for a bluff body introduced in the wind tunnel. Ansys®—Fluent allows the user to realize the potential of obtaining results on a scale model even before physical model testing, thus, saving time and cost involved in physical testing of models. Obtaining precise results and using them in design will economize the structure and render sustainability. Static and dynamic pressure acting on the bluff body and the velocity of wind at various points of interest along the length of the wind tunnel are the findings of this analytical study.
