Critical Heat Flux of R134a and R245fa Inside Small-Diameter Tubes

John Richard Thome, Sylwia Szczukiewicz, Cristiano Bigonha Tibiriça

This article presents new experimental critical heat flux results under saturated flow boiling conditions for a macro/microscale tube. The data were obtained in a horizontal 2.20-mm inside diameter stainless-steel tube with heating lengths of 361 and 154 m ...

Saturated flow boiling heat transfer and critical heat flux in small horizontal flattened tubes

John Richard Thome, Cristiano Bigonha Tibiriça

This paper presents experimental results for flow boiling heat transfer coefficient and critical heat flux (CHF) in small flattened tubes. The tested flattened tubes have the same equivalent internal diameter of 2.2 mm, but different aspect height/width ra ...

Flow Boiling Characteristics for R1234ze(E) in 1.0 and 2.2 mm Circular Channels

John Richard Thome, Cristiano Bigonha Tibiriça

Experimental flow boiling heat transfer results are presented for horizontal 1.0 and 2.2 mm I. D. (internal diameter) stainless steel tubes for tests with R1234ze(E), a new refrigerant developed as a substitute for R134a with a much lower global warming po ...
