Experimental Investigation to Boiling Heat Transfer on a Heated Surface with Multiple Impinging Jets

Abstract:

On the condition of water multiple jet impingements, a steady-state experimental study had been conducted for boiling heat transfer in an atmospheric pressure. The jet velocity was 0.95~1.59m/s and the sub-cooling degrees of jet fluid were 30~83°C.The results revealed that increasing either jet velocity or sub-cooling degrees would promote the heat flux through heated surface, and the effect was more pronounced in partial boiling regime than fully-developed boiling regime. The heat transfer with multiple jets is enhanced due to disturbance of different impingements. With modification of the factor which related to flow distance of fluid on heated surface, correlation which is applicable to one single impinging jet boiling, can also be used to calculate critical heat flux(CHF) in boiling heat transfer with multiple impinging jets.
