tailieunhanh - Experimental study of bubble behaviors and CHF on printed circuit board (PCB) in saturated pool water at various inclination angles

The surface inclination angles were 0 , 45 , 90 , 135 , and 180 . Results showed the Onset of Nucleate Boiling (ONB) heat flux increased with increasing heater orientation from 0 to 90 , while early ONB occurred when the heater faced downwards (135 and 180 ). The nucleate boiling was observed to be unstable at low heat flux (1e21% of CHF) and changed into typical boiling when the heat flux was above 21% of CHF. | Experimental study of bubble behaviors and CHF on printed circuit board (PCB) in saturated pool water at various inclination angles
