대형배관 내부식 코팅공정의 온도 균일성 향상을 위한 와류날개 형상 연구 = A Study on the Temperature Uniformity for the Anti-Corrosion Coating Process of Large-Sized Water Pipes

다국어 초록 (Multilingual Abstract)

In this study, the thermal and fluid dynamic characteristics for the coating process of large-sized water pipes was studied by heating the inside of a pipe directly with a gas burner. Heat and flow analyses were performed on large pipes with various inlet shapes. Using large pipes for coating was shown to be the proper shape for heating large pipes uniformly. This type has a screw with a diameter of 200 mm installed at the inlet to provide a rotational motion to the heating air. The rotational motion resulted in a uniform temperature distribution that ranged from 289.1℃ to 352.1℃ The optimized geometric configuration of the inlet of the pipe successfully and uniformly enhanced the thermal characteristics of the devised temperature limit.
