This paper presents the experimental results for R134a flowing through micro-orifices with diameters of 31 and 52 μm, and length-to-diameter ratio of 2.5 and 4.2, respectively. For liquid flow without flashing, the experimental data were in rough agreement with macroscale results. The conventional orifice equation is still applicable. For liquid flow with… (More)
