Measurement of heat transfer coefficient in two phase flows of radiation-resistant zeotropic C2F6/C3F8 blends
Original language description
We have measured the flow boiling heat transfer coefficient (HTC) of saturated fluorocarbon blends in a horizontal copper-nickel tube with a diameter of 4 mm. Direct (Joule) heating of the tube wall was used to obtain heat fluxes from 5 to 13.7 kW m(-2). Two different injection capillaries were used, permitting measurements at mass fluxes varying between 94 and 164 kg m(-2) s(-1). The evaporation pressure was approximately 0.2 MPa for the mass fluxes close to 164 kg m(-2) s(-1) and 0.15 MPa for the lower mass fluxes. As expected, the HTC in pure C3F8 was higher than in blends with increasing C2F6 content. Nevertheless, the study confirmed that the ATLAS SCT could be operated at full power dissipation with cooling tube temperatures up to 10 degrees C colder than in pure C3F8 with C3F8/C2F6 blends having relatively modest values of HTCs in the range 1500-4000 W m(-2) K-1.
