helicity
In fluid mechanics, helicity is the extent to which helix-like motion occurs. If a parcel of fluid is moving, undergoing solid body motion rotating about an axis parallel to the direction of motion, it will have helicity. If the rotation is clockwise when viewed from ahead of the body, the helicity will be positive, if counterclockwise, it will be negative.
