스팀 트레이싱 시스템 사양 선정 GUI 프로그램 개발에 관한 연구

초록

A graphical user interface (GUI) program for steam tracing system selection was developed by using a theoretical model. We derived the model on the basis of the one-dimensional heat transfer theory of conduction and convection through acomposite wall. Computational fluid dynamics (CFD) and experiments were performed for validation at steam temperaturesof 120.4[℃] and 158.9[℃]. The temperature of a pipe’s outer surface obtained through CFD matched well with that predictedby the proposed model for both conditions. By contrast, the experiment results showed a small error at 120.4[℃] anda large error at 158.9[℃] because of the melting of the heat transfer compound and water phase transition. Thus, thesteam temperature range of the proposed model is below 120.4[℃].
