Design And Analysis Of An Aerodynamic Window Lintel For Air Drag Reduction On A Square Cros Sectional Structure

Abstract

Every building must be provided with some way of ventilation or a streamlining design to reduce the air drag and turbulence, in order to prevent stress on the underlying pilings. Every multistorey building in a cosmopolitan city is constructed with a non-rectilinear structure such as helical, circular, etc to be a streamlined structure. For the vent/passage of air, there are some cases where they left an entirety of a floor to ensure air passage. But, looking at the layout we can conclude that there is a massive waste of the carpet area/ living space. So, in order to reduce the effect of turbulent air on a regularly shaped building, a modification in the design of the regular window lintel is made. A normal window frame/lintel, which is usually provided for shade and as a canopy, is constructed with bricks and cement. Considering a sample lintel, it has more than 2 feet in depth. Now, using this length can be made a design that can reduce the turbulence of the air that is passing through the building. This helps us to reduce the air drag and stresses on the building’s pilings or joints, without wasting much of the area. Considering the elevation, the design will be made to look aesthetically pleasing. A comparative study will be made with respect to the published papers and past theories.
