Abstract

This paper is concerned with analysis of the turbulent flow over dimpled aerofoil profiles. Dimples of varying aspect ratio are used to study the effects on the skin-friction drag and lift. An external flow study was performed using ANSYS FLUENT. Simulations for external flow configuration with and without dimples were carried out and analyzed in detail. The resulting pressure drop and drag were observed. The objective was to clarify whether or not dimples cause reduction of the skinfriction drag and if it would provide better lift.
