The Characteristics of Boiling Heat Transfer of R-600a-oil Mixture in a Circular Tube with Porous Inserts

Abstract:

This investigation was carried out to study the characteristics of boiling heat transfer for hydrocarbon refrigerant R600a (isobutane)/oil mixtures flowing in a circular pipe within dispersed-copper porous inserts. The oil was the EMKARATE RL 32H with a viscosity 150 SUS. The test was conducted at a saturation temperature of 10 , vapor qualities from 0.076 to 0.87, inlet oil concentration from 0 to 3 mass% oil, mass flux of 120 1100 and heat flux of 12-65 . The effects of the concentration of the refrigerant/oil mixtures, and the sizes of inserts on the heat transfer of R-600a for present study were presented.
