... be closed. Here, the mixture was made by weighting out the components under air contact. Then, a degassing procedure was applied, which is recommended in Ref. 23 for heat pipe fluids. Therefore, the liquid mixture is filled into a round bottom flask, closed and frozen with liquid nitrogen. When the fluid...

... a maximum decrease by a factor of 2 relative to that for pure R134a. At the azeotropic point (65% R290), it was found to increase by a factor of 1.2. The measured local heat transfer coefficients for both R134a and R134a/R290 were compared with a number of correlations. boiling heat transfer liquid...

... liquid mixtures, concentration result in a change in the liquid index of refraction, which alters the reflectivity of the liquid surface. An intensity-stabilized diode laser and silicon photodiode are used to monitor the surface reflectivity. Temperature variations in 1-propanol, methanol, ethanol...
