Type of article: Article

Summary

As opposed to similar tests with a microfin tube, no evidence of oil holdup inside the plain tube test sections was noted. However, the effect of flow pattern appears to be important; the effect of local physical properties on the heat transfer coefficient at high vapour qualities was confirmed.
