A Real-Time Thermal Test Platform for Underwater Complex Structures and Heat Transfer Analysis

In order to conduct an effective and reasonable heat transfer analysis, a real-time thermal test platform was established, which consists of two flow loops, the heating system, the data acquisition system, the automatic data processing software and the relative piping system. Based on this platform, a typical T-type deadleg and a gate valve assembly are adopted to investigate their heat transfer characteristics. The experiment data are compared with the numerical calculation with great good agreements. For further application, this real-time thermal test platform could be used for cool down analysis and thermal insulation assessment. Ultimately, promotional values for similar and even much larger scale complex underwater structures could be found in this study.
