摘　　要：利用CFD方法计算某内河大型自航绞吸挖泥船在浅水状态下的总阻力。在不同水深及不同航速下对船模周围流场进行数值模拟,计算过程考虑自由面的影响。将计算结果与模型试验作比较,计算结果有较高的可靠性。并通过分析这类船型的流场分布进一步理解船舶在浅水航行中的阻力成因。The CFD method ＆ applied to calculate the resistance in shallow water for a cutter suction dredger which is an inland large vessel. Taking the free-surface effect into consideration, the flow field around the ship at different depth and different speed is numerically simulated. The calculated result is compared with the experimental result. The calculated result is more reliable. Through the analysis of the flow field of this kind of ship, it can be further understood that the resistance causes of ship in shallow water.
