Abstract

Abstract:

The structure and adiabatic mode of a new Type B liquefied natural gas simulator cabin are introduced and a low temperature test device for adiabatic effect is built. The temperature distribution of the adiabatic layer in the simulated cabin under the condition of breakage is tested, and the experimental results show that the evaporation rate of the local liquid nitrogen in the simulator is 2.138%/d, which increases by 0.226%/d compared with the insulating layer intact condition. It can be concluded that the damage of the local adiabatic structure has influence on the adiabatic performance of the simulator and the ship. The research results provide an important reference for the development and design of LNG cargo tank.

摘要：

介绍了新型B型液化天然气模拟舱结构和绝热方式，搭建了模拟舱绝热效果低温测试装置，测试了破损工况下模拟舱绝热层的温度分布情况，然后得出了模拟舱的当地液氮蒸发率2.138%/d，与绝热层完好工况相比增加0.226%/d。由此可知，局部的绝热结构的损坏对于模拟舱和实际船舶的绝热性能有很大影响。研究结果为LNG船液货舱的开发设计提供重要参考。
