Abstract: The pressure effects of expanding the cross section of microchannels along the direction of flow are investigated across four rates of channel expansion in the flow boiling of R134a. Prior investigation by the authors ...

Abstract: The effect of an expanding microchannel crosssection on flow boiling critical heat flux (CHF) is experimentally investigated across four rates of expansion. A pumpedloop apparatus is developed to boil R134a in an array of ...

Abstract: This study discusses the simulation of flow boiling in a microchannel and numerically predicts the effects of channel geometry variation along the flow direction. Experimental studies by Pan and collaborators and suggestions ...
