본 연구에서는 종횡비가 2인 직사각형 용기에 대한 스핀업 유동을 실험과 수치해석으로 연구하였다. 수치해석에서는 1차-, 2차- 에크만 펌핑 모형을 사용한 경우와 평정을 무시한 경우에 관해 유동장을 구하였으며, 실험에서는 고전적인 PIV 방법을 통하여 속도장을 구하였다. 연구결과, 1차-, 2차- 에크만 펌핑 모형은 실험과 유사하게 나타났으며, 펌핑을 무시한 경우는 상이한 유동양상을 보였다.

In this paper, we show the numerical and experimental results of two-dimensional fluid motions inside a rectangular container with a vertical plate subjected to a background rotation added by a rotational oscillation. In the PIV experiment we apply a new algorithm, NTSS, to the velocity calculation. In the numerical computation, the linear Ekman-pumping model was used to take the bottom friction effect into account. It was found that it showed good agreement with the experimental results at low ${\epsilon}$ number.

In this paper, we show the numerical and the experimental results of two-dimensional fluid motions inside a rectangular container subjected to a background rotation added by a rotational oscillation. In the PlY experiment we apply a new algorithm, new three step search(NTSS), to the velocity calculation. In the numerical computation, the linear Ekman-pumping model was used to take the bottom friction effect into account. It was found that it well produces the experimental results at low e number.
