摘要

为了确定具有自航能力的自升式平台主机功率,分别采用缩尺比模型拖曳试验与CFD数值计算两种方法计算设计航速下平台模型的静水阻力,分析阻力中各主要成分的比重,结合实尺度平台CFD计算结果对实际平台的阻力和主机功率进行估算,试验与数值分析结果均表明,平台首部存在水流堆积现象,平台的粘压阻力较大,占总阻力中的比重也大;采用二因次法从缩尺比模型阻力推算到实尺度平台阻力会有较大误差,采用实尺度CFD计算方法给出较为合理的平台主机功率估算结果.

Abstract

In order to determine the main engine power of the self-propelled platform,the hydrostatic resistance of the plat-form model at design speed was studied with towing resistance test and CFD method respectively.The proportion of each main component of resistance was calculated.The main engine power of the actual platform was estimated.The test results and numeri-cal simulation results showed that the water flow accumulation and wave surface uplift are observed in front of the platform;the viscous pressure resistance of the platform is relatively large,accounting for a large proportion of the total resistance;there is a big error in calculating the resistance from the scale model to the real scale platform by using the two-dimensional method.A more reasonable estimate of the main engine power of the platform is given by using the real-scale CFD method.
