基于Fluent的船体界面阻力分析

摘要

基于 Fluent对船体界面阻力进行仿真分析，采用 VOF的方法模拟船体在空气和水两相中的运动情况，获得不同航速下船体摩擦阻力和压差阻力的关系。考虑方型系数对于船体阻力的影响，建立多个方型系数不同的模型来实现Fluent仿真模拟，获得一定傅汝德数下船体方形系数与船体阻力的关系，得到船舶阻力相对优化的船型。该方法通过更加精确的建模可为船体型线减阻提供更多的依据。%Hull interface resistance was calculated by FLUENT simulation analysis.VOF method was used to simulate the hull in two phases of air and water movement, and the relationships of different speed hull friction and residual resistance was studied. Considering the influence of block coefficient on resistance, simulating in fluent by establishing multiple models of different block coefficient, concluded the relationship between resistance and hull block coefficient when the Froude Number of a certain time, get the relatively optimized ship resistance. This method is more accurate modeling which can provide more evidence for the hull lines of drag reduction.
