Numerical Analysis of the Influence of Side Slot and Fin Heights in a Hypervapotron Channel on Heat Transfer
Hypervapotron is a water-cooled device which relies on internal fins and boiling heat transfer to sustain ultra-high heat flux in the range of 20–30 MW/m2 from thermonuclear fusion reactor. This study investigated the design optimization of hypervapotron cooling channels using multiphase computational fluid dynamic simulation. With focus on geometric variations in fin heights and side slots installed to the cooling channel, their effects on the cooling performance and internal flow pattern of these channels were evaluated. The obtained results revealed that the incorporation of side slots significantly enhanced cooling performance by promoting bidirectional fluid inflow and optimizing heat dissipation. It was also found that adjusting fin heights significantly contributed to improved thermal management by ensuring smoother liquid ingress and effective heat exchange. This work established a link between design variations and cooling performance, providing insights and guidelines for advanced engineering of hypervapotron systems.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
