考虑到局部流场是控制和决定流冰在隔水套管区内运动形态的关键因素,使用FLUENT软件,对渤海浅水重冰区某导管架平台的隔水套管区内的流场进行数值模拟,统计可能发生碎冰滞留的区域分布比例,并根据不同入流方向进行评估,结果表明,隔水套管区内局部流场的滞留效应是导致碎冰堆积的主要诱因.
攷慮到跼部流場是控製和決定流冰在隔水套管區內運動形態的關鍵因素,使用FLUENT軟件,對渤海淺水重冰區某導管架平檯的隔水套管區內的流場進行數值模擬,統計可能髮生碎冰滯留的區域分佈比例,併根據不同入流方嚮進行評估,結果錶明,隔水套管區內跼部流場的滯留效應是導緻碎冰堆積的主要誘因.

Local flow field is the key factor affecting the motion patterns of the drift ice in the region of the drill conductor. The FLUENT software is used in to simulate flow field of the region of conductor of a jacket platform in the shallow area with heavy ice in Bohai sea.The distribution of possible regions of rubble ice retention is counted, and the results are evaluated ac-cording to different inflow directions.The numerical results show that the local flow field in conductor area of the retardation effect is the main causes to lead to accumulation of crushed ice.
