根据胆囊收缩特点及胆汁属性提出了收缩胆囊内胆汁流动的数学模型，采用ＳＩＭＰＬＥＲ算法计算了活体胆囊收缩时胆汁流动的速度分布及压力分布。计算结果表明，胆囊收缩时，囊内出口附近区域存在明显的Ｓ型旋涡区域，该区域的存在有可能是形成胆囊结石的重要条件。
On the basis of the features of contracting gallbladder and properties of gallbladder bile,the mathematical model of bile flow in a living contracting gallbladder is proposed,the velocity distribution and pressure distribution are calculated by SIMPLER method.The results show that there exist obvious S vorteices near the exit, which probably form the important conditions of cholecystolithiasis.
