Study of heat transfer in a 7-element bundle cooled with the upward flow of supercritical Freon-12
… One of the SC modeling fluids typically used is Freon-12 (R-12) where the critical pressure is 4.136 MPa and the critical temperature is 111.97ºC. These conditions correspond to a critical pressure of 22.064 MPa and critical temperature of 373.95ºC in water. A set of experimental data obtained in …

An experimental simulation of liquid fuel injection into a heated subsonic gas crossflow
… was accomplished through injection of chilled Freon-12 into the Virginia Tech 23 x 23 cm. blow-down wind tunnel at a freestream Mach number of 0.44. The freestream stagnation pressure and temperature were held at 2.5 atm. and 300°K respectively. The resulting spray plume was carefully examined …

The determination of the viscosity of liquid carrene-7, an azeotropic mixture of dichlorodifluoromethane and asymmetrical difluoroethane
… as ammonia, sulfur dioxide, methyl chloride, freon-12 (dichlorodifluoromethane), and propane are used. These refrigerants must have properties that render them suitable for use in refrigeration cycles. During the refrigeration cycle, the refrigerant is constantly changing state; that is, from …

A comparative study of freeze-thaw processes for conditioning wastewater and water treatment sludges
… hydrate or clathrate formation by addition of Freon 12 under appropriate temperature and pressure conditions. Sludges were also frozen solid using indirect freezing methods, thawed and tested for comparative purposes. Particle size distribution and floc density measurements were used to …

The entrainment and homogenization of tracers within the cyclonic gulf stream recirculation gyre
… fluxed into the NRG include salt, oxygen, and freon. These particular tracers are independent from each other, the former two because they are characterized by different vertical profiles in the deep layer. This results in a decay of oxygen but not salt, due to the presence of vertical mixing …
