A study of in-tube evaporation heat transfer of carbon dioxide.
Author(s) : SAWANT N. N., KIM M. S., PAYNE W. V., et al.
Summary
The evaporative heat transfer characteristics of CO2 were measured in a fluid-heated, 8.0 mm ID smooth stainless steel tube. The test apparatus was a concentric tube heat exchanger heated by water in the annulus with CO2 in the central tube. Data were collected for temperatures of 5 and 10 °C; mass fluxes of 250, 500 and 650 kg/m2s; and heat fluxes of 24 to 58 kW/m2. The average heat transfer coefficient was determined with the overall UA equation for the annular configuration. Results are presented and compared to existing correlations for the two-phase average evaporative heat transfer coefficient.
