Measuring of critical density of heat flow during boiling of nanoliquids on a cylindrical heater

Saturated boiling of nanoliquids on a cylindrical heater is experimentally studied. The studied nanoliquids were prepared using distilled water and Fe3O4 iron oxide or diamond nanoparticles. The volume concentration of the nanoparticles was changed from 0.25 to 1%. It has been measured that the critical density of heat flow in nanoliquids is far higher than in water. Moreover, it depends on size of nanoparticles.
