An accurate prediction of the interphase behaviors vertical gas-liquid subcooled boiling flow is meaningful for first loop a nuclear power plant (NPP). Therefore, including bubble size distribution in NPP are analyzed, evaluated, and validated using various wall models coupled with population balance model (PBM) kernels this paper. Firstly, nondimensional numbers DEBORA (Development Borehole Se...

An 820-Watt clamshell module was fabricated and tested in order to assess the feasibility of cooling future high heat flux avionic hardware via subcooled phase change. One half of the module was constructed from aluminum 7075-T6 and populated with 16 heat sources simulating microelectronic chips. The other half was substituted with a transparent plastic cover to facilitate optical access to the...

Excellent heat transfer performance has increasingly become a key issue that needs to be solved urgently in the development process of large-scale fusion equipment. The study improvement scientifically and reasonably determine design parameters high flow (HHF) components reactors based on efficient in-depth analysis mechanism its sensitive factors is great significance. In this paper, liquid-va...

In the current research project, two-dimensional numerical simulations are conducted to analyze effects of geometrical configuration on flow structures and thermal performances subcooled boiling. The CFD carried out in two different configurations (straight periodic constriction expansion) a minichannel mounted vertically at four mass fluxes (500 kg/m2s; 836.64 1170 2535 kg/m2s). present predic...
