- •
Flow boiling characteristics of R134a and R407C were studied in a micro-channel.
- •
The phenomena of advance into churn-annular flow and coexistent bubbles were observed for R407C.
- •
The nucleate boiling heat transfer of R407C is suppressed during bubbly flow.
- •
A correlation with Marangoni number was developed for zeotropic mixtures.
