摘要

众所周知，为了为任何类型的水面舰艇提供防火保护，外部消防(EFF)系统已经普遍使用了几十年，在沿海地区也是如此。这些类型的系统存在于几种类型的船舶上，如消防船、拖船、补给船和海军舰艇。流量调节器可用于EFF系统，通过调节fi-fi监视器内的流量来提供更好的性能。本研究设计了一种消防(fi-fi)监视器，并在该监视器中安装了不同的流量调节器。在ISO 5167-3推荐的流量调节剂基础上，设计了一种独特的流量调节剂，以提高流量调节剂在水头比和流量方面的性能。利用商业计算流体动力学(CFD)求解器对不同的气流调节器的性能进行了研究。在比较不同流量调节器的数值结果之前，将数值模型与实验数据进行了验证，并采用相应的方法进行了验证。结果表明，该独特的流量调节剂对流线的调节效果良好，在流量和水头比方面优于ISO 5167-3推荐的调节剂。作为研究的最后一部分，研究了不同流量调节剂长度的影响，并确定了最佳长度。

AN EXTENSIVE INVESTIGATION OF FLOW CONDITIONERS INSIDE A FI-FI MONITOR

As it is known, to provide fire protection for any type of surface vessel, external fire-fighting (EFF) systems have been commonly used for decades as well as in coastal regions. These types of systems exist on several types of vessels such as fire-fighting ships, tugboats, supply vessels and naval vessels. Flow conditioners can be used in the EFF systems to provide better performance by regulating the flow inside the fi-fi monitor. In the present study, a fire-fighting (fi-fi) monitor was designed and different flow conditioners were implemented into the fi-fi monitor. A unique flow conditioner was designed in addition to the recommended ones by ISO 5167-3 in order to improve the performance of the flow conditioner in terms of head ratio and flow rate. A commercial computational fluid dynamics (CFD) solver was used to investigate the performance of the different flow conditioners. Before comparing the numerical results of different flow conditioners, the numerical model was validated with the experimental data and verified with appropriate methods. The results showed that the unique flow conditioner successfully regulates the streamlines and it has better performance than the recommended ones by ISO 5167-3 in terms of flow rate and head ratio. As the last part of the study, the effect of unique flow conditioner length was investigated and the best length was determined.
