Measurements of local heat transfer coefficients during the evaporation of R404A inside a horizontal tube.

Author(s) : BOISSIEUX X., JOHNS R. A., HEIKAL M. R.

Summary

The results have been compared with existing correlations characterising the evaporative heat transfer coefficient to assess the suitability of these models with mixtures. The Gungor and Shah correlation predicted the results well over a 0.2 to 0.8 vapour quality range, but did not accurately predict the dry-out at high vapour quality. This process is the basis for a correlation development.
