Flow Around a Comb Wing in Low-Reynolds-Number Flow

d = spacing between two adjacent cylinders/bristles normalized by L eb = unit vector in the binormal direction (normal to both en and et) en = unit vector in the normal direction (normal to the wing’s plane) et = unit vector in the tangential direction (in the direction of the cylinder/bristle length) L = half-length of the cylinders/bristles, m m = number of cylinders/bristles Re = Reynolds number based on wing semispan s = coordinate along cylinder/bristle length, m U1 = velocity of the wing, m=s x = coordinate along the root of the wing whose origin is in the vehicle’s shoulder, m " = rod radius normalized by L
