Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

PPPL study points to better fusion plasma control
The combination of two previously known methods for managing plasma conditions can result in enhanced control of plasma in a fusion reactor, according to a simulation performed by researchers at the Department of Energy’s Princeton Plasma Physics Laboratory.

The effect of the hypervapotron (HV) fin angle on heat transfer was analyzed through visualization experiments and subcooled flow boiling experiments. An HV channel with a fin angle of 45 deg had a higher onset-of-nucleate-boiling heat flux than the typical HV channel. Additionally, as the heat flux increased, the bubble-sliding effect caused by the tilted fin was visualized, and it was observed that the vapor inside the fin was agglomerated by the sliding flow and driven into the side slot. When the fin angle of the typical HV channel was set as 0 deg, as the tilted angle of the fin increased, the heat transfer and critical heat flux (CHF) were improved owing to the secondary flow generated by the sliding effect. When the fin angle reached 45 deg, the CHF value was improved by 81% compared with the typical HV channel, which was the highest enhancement rate among the evaluated HV channels. However, when the fin angle exceeded 45 deg, the vapors aggregated more rapidly as the sliding velocity induced inside the fin increased. Furthermore, the two-phase pressure drop was analyzed through differential pressure measurements. The 45-deg tilted HV channel had a higher onset-of-significant-void heat flux value than all the other channels (HV, swirl, smooth, flat channels).
