Modelling of Boiling Flows for Nuclear Thermal Hydraulics Applications—A Brief Review
Inventions, 2020 The boiling process is utterly fundamental to the design and safety of water-cooled fission reactors. Both boiling water reactors and pressurised water reactors use boiling under high-pressure subcooled liquid flow conditions to achieve high surface heat
