The wall film-wise condensation plays an important role in the heat transfer processes of exchangers, refrigerators, and air conditioner. In field nuclear engineering, steam is often utilized safety systems to remove core decay under both transient accident conditions. particular, passive containment cooling system (PCCS), are designed ensure severe A computational fluid dynamics (CFD) scale analysis has been conducted calculate rate PCCS. However, despite increase computing power, there...

Recently, diverse marine applications of nuclear power are being considered to meet the carbon reduction goals in maritime industries. One distinctive characteristics reactors is limit space and it requires high density. To address this problem, tight lattice bundle with a helical shaped non-circular fuel rods can be employed. However, critical heat flux (CHF) mechanisms for such alternative have not been adequately investigated experimentally. In particular, no open-access CHF experiment...
In a floating nuclear reactor, the prediction of critical heat flux (CHF) is crucial because CHF can be influenced under heaving, rolling, and inclination conditions compared with case in land-based reactor. Therefore, existing empirical correlations invalid some marine this study, flow boiling were proposed to predict rolling motions tubes annuli. Available experimental databases collected, their trends analyzed. According previous studies, inclined was generally reduced but enhanced The...
Floating nuclear power plants have attracted significant attention as a prospective means to deliver clean energy, particularly in geographically remote areas where conventional infrastructure is inaccessible. The ocean environment, however, can affect the thermal-hydraulic phenomena them. Notably, two-phase system, CHF change due periodic variation of additional forces. While few experimental studies been conducted on under heaving motion, expanding range test conditions necessary elucidate...
