Experimental View on Performance of Flow Past Over a Symmetrical Aerofoil at Low Subsonic Speed

Abstract

This paper brings us the aero dynamics properties of flow over symmetrical aerofoil (NACA-0012) at low subsonic speed (M<0. 3). Generally symmetrical aerofoil are used in supersonic aircraft for military purpose like fighter and bomber to give smooth speed at supersonic speed (M> 1) and including compressible effect. Here attempt has been made to determine pressure distribution over symmetrical aerofoil at low sub-sonic speed and in viscid incompressible flow. The flow behavior on symmetrical aerofoil of upper and lower side has been investigated.
