Objectives: To provide comprehensive literature survey of laminar separation bubble over a low Reynolds number airfoil with reference to the conventional experimental technique using wind tunnel .
The current evidence supports the view that laminar separation bubble ,characteristics behavior and its effect over a airfoil . Most studies in this field have been done experimentally using wind tunnel, with various technique that is one of the technique is surface oil flow technique . XIAMETER PMX-200 20cs silicon fluid was used for this experiment.
Application :This paper describes the various technique and characteristics of LSB which will be beneficial to design the low Reynolds number airfoil in order to minimize the drag and increases the aerodynamics efficiency for industrial application.
