  3. Evaporation of pure fluids and mixtures in a microchannel tube

    Li, HoupeiUniversity of Illinois at Urbana-Champaign2019

    … microchannel tube. Six pure fluids (R134a, R32, R1234ze(E), R1234yf, R1233zd(E), and R1336mzz(Z)) are tested, and they have significant difference in properties. The experiments are conducted in a 24-port microchannel tube with an averaged hydraulic diameter of 0.643 mm. The tested microchannel …
