The invention relates to the technical field of ship overall arrangement, and discloses a living building and chimney arrangement method which comprises the following steps: step 1, simulating turbulence intensity distribution of a flow field around a chimney to obtain turbulence intensity distribution of the flow field; 2, drawing a curve graph of the maximum turbulence kinetic energy kappa of the flow field and the change of the kinetic energy E of the fluid medium under the condition that the spacing ratio gamma of the distance from different chimneys to the living building to the characteristic length of the chimney in the flow field is, selecting a natural logarithm lnE of which E is equal to 0.5 rho v2 as an axis and a turbulence intensity peak value kappa as another axis, obtaining a change curve of turbulence intensity with different gamma values along with wind kinetic energy; and 3, selecting a gamma curve characteristic value with relatively small turbulence energy as a principle for optimizing the arrangement method of the living building and the chimney. The device can simply and effectively simulate the accumulation concentration of the flue gas discharged by the chimney, so that the chimney and the living building are arranged, accumulation of chimney tail gas near the living building can be effectively reduced, and the problem that the living building area is affected by the tail gas discharged by the chimney is effectively solved.
本发明涉及船舶总体布置技术领域,公开了一种生活楼与烟囱布置的方法,包括以下步骤:步骤一:对烟囱周围的流场湍流强度分布进行模拟,得到流场的湍流强度分布;步骤二:绘制不同烟囱到生活楼距离与烟囱在流场中特征长度的间距比γ条件下的流场最大湍流动能κ与流体介质动能E变化的曲线图,选取E=0.5ρν2的自然对数lnE作为一轴,湍流强度峰值κ为另一轴,得不同γ值的湍流强度随风动能变化曲线;步骤三:选取湍动能较小的γ曲线特征值作为优化生活楼和烟囱的布置方法的原则。本发明能够简便有效的模拟出烟囱排出烟气的积聚浓度,由此布置烟囱和生活楼,能够有效降低烟囱尾气在生活楼附近的积聚,有效改善生活楼区域受到烟囱排出尾气影响的问题。
