摘　　要：为评估船舶快速性,采用两相流自由面VOF技术计算船舶阻力,用带有升力面修正的升力线法计算螺旋桨敞水性能,用非均匀来流的升力线法计算伴流分数和相对旋转效率,用鼓动盘理论计算推力减额。数值计算的结果与模型试验的结果相近。通过数值计算方法将虚拟试验替代模型试验,在保证精度前提下采用较简捷的方法,希望推动虚拟试验的方法朝快捷、高效的方向发展。Powering performance is one of the important parameters in ship design, and model test is generally carried out to evaluate this performance. In this paper, resistance of the ship model is calculated by using VOF technique on water surface, and open-water characters of the propeller model are calculated by applying lift line theory with lift surface correction, and the wake and relative rotate efficiency are gotten by non-uniformity flow lift line theory, and thrust deduction fraction is calculated by agitation disk theory. The calculation result is closed to the test result. A simple and efficient method of virtual test instead of the model test is presented.
