| 1 | Numerical Modeling of Exhaust Smoke Dispersion for a Generic Frigate and Comparisons with Experiments显示文摘为一艘通用护卫舰的 exhaust 烟分散通过管理液体流动,精力,种类和骚乱方程的数字答案数字地被调查。这个工作的主要目的是在 exhaust 烟的分散上获得 yaw 角度,速度比率和快活的效果。数字方法基于充分椭圆形的海军司烧方程的充分保存的控制卷表示。骚乱被建模用一二方程(k-?) 模型。用在风隧道的护卫舰的一个 1/100 规模模型的流动可视化测试也被执行决定 exhaust 羽毛路径并且验证计算结果。结果显示出那在下面洗现象为在蠄 =10 掳和 20 掳之间的 yaw 角度发生。结果与不同用尽快活效果与增加 exhaust 气体温度增加的煤气的温度表演。然而,它在羽毛上升的效果与它的动量比较是不太重要的。在预言和实验结果之间的一个好协议被获得。 | Selma Ergin Erinc Dobrucah | 2014 | Journal of Marine Science and Application2014，13，2： | 0 |
| 2 | 温度、盐度和流体类型对圆柱周围湍流声学特性的影响研究显示文摘The effects of the temperature,salinity,and fluid type on the acoustic characteristics of turbulent flow around a circular cylinder were numerically investigated for the Reynolds numbers of 2.25×10^(4),4.5×10^(4),and 9.0×10^(4).Various hybrid methodsReynolds-averaged Navier-Stokes(BANS)with the Ffowcs Williams and Hawkings(FWH)model,detached-eddy simulation(DES)with FWH,and large-eddy simulation with FWH-were used for the acoustic analyses,and their performances were evaluated by comparing the predicted results with the experimental data.The DES-FWH hybrid method was found to be suitable for the aero-and hydro-acoustic analysis.The hydro-acoustic measurements were performed in a silent circulation channel for the Reynolds number of 2.25×10^(4).The results showed that the fluid temperature caused an increase in the overall sound pressure levels(OASPLs)and the maximum sound pressure levels(SPL_(T))for the air medium;however,it caused a decrease for the water medium.The salinity had smaller effects on the OASPL and SPLT compared to the temperature.Moreover,the main peak frequency increased with the air temperature but decreased with the water temperature,and it was nearly constant with the change in the salinity ratio.The SPLT and OASPL for the water medium were quite higher than those for the air medium. | SertaçBulut Selma Ergin | 2021 | Journal of Marine Science and Application2021，20，2： | 0 |
