Critical heat flux enhancement in saturated pool boiling using water-based nanofluid with honeycomb porous plate

The critical heat flux (CHF) limit is a great concern by many in the field of heat removal technology through pool boiling system. External cooling of pressure reactor vessel by in-vessel retention (IVR) method will involve boiling process in order to remove decay heat from the molten core through...
