Effects of oil on boiling of replacement refrigerants flowing normal to a tube bundle. 1. R123.

Author(s) : TATARA R. A., PAYVAR P.

Summary

Local experimental heat transfer coefficients have been obtained for boiling refrigerant flowing up and across a tube bundle segment representing a full flooded evaporator tube bundle. The refrigerant enters at 15% vapour quality and exits at nearly 100% vapour in order to simulate an actual flooded evaporator bundle. Both heat flux and oil content, 0 to 15% (by weight), are varied; the mass flux is not varied independently but set by the heat flux. Local tube and bulk fluid temperatures are measured directly, by thermocouples.
