抄録
This paper presents a particle tracking technique using rotational invariant in PIV. Using combinational techniques of PIV, it is difficult to correctly track tracer particles in strongly rotational flow because there is not a little difference in particle pattern between before moving and after. Rotational invariant is expected to be effective in order to improve particle tracking accuracy in rotational flow. In this paper, particle pattern in three-dimensional space has been made and rotated by numerical simulation, and then rotational invariant is computed for various rotational angles in order to confirm the effectivity of rotational invariant in three-dimensional image rotation. As a result, it is shown that rotational invariant is constant for any rotational angle in three-dimensional particle model.
