Experimental study on the effect of magnetic field on critical heat flux of ferrofluid flow boiling in a vertical annulus

In the present work, effects of using magnetic nanofluid and also applying an external magnetic field on the critical heat flux (CHF) of subcooled flow boiling has been studied experimentally. The experiments have been applied in upward flow direction in a 12 mm I.D., 19 mm O.D. and 0.75 m length annular test section. Inlet subcooling was kept constant and the mass flux was varied in the range of 0–150 kg/m2 s while the exit was at atmospheric...
