Experimental Study on the Flow Boiling Heat Transfer Characteristics in a Mini-Channel with Offset Fins
The present study studied the flow boiling heat transfer performance of a mini channel with offset fins experimentally. The hydraulic diameter for it is 1.59 mm with 9 offset rectangular channels. The influences of saturation pressure, mass flux and heat flux on heat transfer coefficient were invest...
