EXPERIMENTAL INVESTIGATION OF PARAMETERS INFLUENCING WIND ENVIRONMENT AROUND BUILDINGS

Abstract

Presence of an interfering building on the upstream side of an object building alters the wind environment around the object building. Present study describes the results of the experimental study carried out on rigid models of buildings in a boundary layer wind tunnel in order to study the amount by which wind environment will get changed due to the relative dimensions and arrangements of the interfering building in the near vicinity. Model of interfering building is placed on the upstream side of the object building model. Spacing between the models is varied and wind velocity measured between them. Further, height of interfering and object building models is varied to study the influence of relative dimensions on wind velocity. Beside these, another two cases have also been considered in the present study, i.e. two object buildings models are placed side by side and face to face with or with-out the rear side building. The spacing between the two object buildings models is varied and mean wind velocity between them measured
