Analytical Study of Unsteady Boiling Characteristics of Steam Generator

Currently, research on the efficiency of film heater, which is a surface heating element, being actively conducted as it potential alternative to sheath heater. However, heat transfer phenomenon and performance heater insufficient. In this study, were compared analyzed, pattern according arrangement wire was analyzed. To inspect performance, external internal flow characteristics steam generator determined, study each design variable conducted. The Eulerian multiphase model used conduct analysis, wall boiling phase change analysis. Among models analyzed in arranged along path length induction extended by 50% showed best performance. Compared base model, generation time improved 33.3% ejection 17%. These times because optimized fluid channel. U-shaped enabled stable injection, case normal channel following large portion located around center. Consequently, formed at center housing. We believe that results can be applied various fields consideration advantages package, free printing, economy.
