2. MOTIVATION AND APPLICATION
•Wing of insect are corrugated.
•Flight are under low Re Regimes.
•Micro Air Vehicles (MAVs) are as small as
15 cm, weight about 90 gram and have a
flight speed of about 10 m/s.

Remarks
Kesel (2000) corrugated Re=
10000
Experimental corrugated airfoil produce much
higher lift
Murphy and
Hu (2010)
corrugated Re =
58000
and
125000
Experimental vortex structures that formed
inside the valleys of the
corrugation and peak of
corrugation promoted the flow
transition from laminar to
turbulent.

corrugated - Experimental earlier reattachment of the flow
separation on the corrugated
wings, hence lift increases.
Meng and Sun
(2013)
corrugated Re =
200-
2400
Numerical Negative effect on aerodynamic
performance as lift decreases and
slight change in drag coefficient.

4. OBJECTIVE
•To see the flow pattern formed
around the corrugated airfoil at
various Reynolds Number.
•Comparison of flow pattern for
different corrugations.
•Also calculate the force coefficient
