计及升沉与纵倾的船舶阻力预报
PREDICTION for SHIP RESISTANCE CONSIDRING SINKAGE and TRIM
中高速船舶航行时其姿态与静浮相比有较大的变化,这将显著地影响船舶阻力。因此对此类船舶的阻力预报问题,需将船舶的航行姿态求解作为解的一部分;目前国内外的部分学者基于不同的方法对此类船舶计及航态的绕流场求解问题进行了部分研究;本文采用求解水面船舶绕流场RANS方程的方法,以欧拉显式向前差分求解船舶的姿态时历,通过动网格技术保证计算域连续;船舶的航行姿态以及阻力计算结果表明该方法对于此类船舶的阻力预报问题具有一定的可行性。
Navigation gesture of vessels sailing at medium or high speed is much different from that at still, which will affect the resistance performance. So it's necessary to take sailing gesture solution into account when predicting ship resistance. In recent years, many scholars takle this problem in different ways. In this paper, RANS solution is adopted to simulate the flows around surface ship, and Eulerian-explicit difference scheme is used to solve time history of navigation gesture. The result shows that the approach is feasibile to predicte the resistance of such kind of ships.
