Flow boiling of refrigerant-oil mixtures: inverse methods for heat transfer coefficient measurements.

Summary

A test section and numerical methods for the determination of the distribution of the heat transfer coefficient at the inner surface of a smooth tube are presented. Test data show the influence of a commercial ISO Grade 68 lubricant on flow boiling of refrigerant R134a. The sensitivity of the boundary element method due to measurement errors is discussed.
