A Simple Equation for the Thermal Conductivity of Saturated Vapor Refrigerants
The ability of a material to supply heat by means of conduction is called thermal conductivity, which is defined by Fourier's equation. Thermodynamic data on environmental refrigerants have attracted considerable interest in the design and optimization of refrigeration equipment, such as heat compressors and exchangers. After analysis of statistical effects, a new simple correlation was develop...
متن کاملThermal Conductivity of Nanoparticle–Fluid Mixture
Effective thermal conductivity of mixtures of uids and nanometer-size particles is measured by a steady-state parallel-plate method. The tested uids contain two types of nanoparticles, Al2O3 and CuO, dispersed in water, vacuum pump uid, engine oil, and ethylene glycol. Experimental results show that the thermal conductivities of nanoparticle– uid mixtures are higher than those of the bas...
متن کاملVapor-phase Thermal Conductivity of Binary Mixtures of Cyclopentane and R134a with R365mfc
The thermal conductivity of mixtures of R365mfc (1,1,1,3,3pentafluorobutane), with R134a (1,1,1,2-tetrafluoroethane) and cyclopentane were measured using a transient hot-wire method, in the pressure range between 0.1013 and 0.7MPa and temperatures between 311 and 413K. The composition of the measured mixtures was 93.0% R365mfcþ 7.0% R134a (kg/ kg), 27.0% R365mfcþ 73.0% R134a (kg/kg) and 62.8% R...
متن کاملPHASE STABILITY AND CONDUCTIVITY OF δ-Bi2O3 WITH MIXTURE OF YTTRIUM AND YTTERBIUM OXIDES
In this research Bi2O3 was doped with mixtures of 8, 10, 12 and 18 mol % of Y2O3 and Yb2O3 to stabilizing the δ-Bi2O3 phase using solid state reaction technique. Experimental samples were fabricated by isostatic pressing and sintering at 850 °C for 24 h. X-ray diffraction analysis detected cubic phase (δ-Bi2O3) as the sole stable crystalline phase in samples including 12 and 18 mol % of Y2O3 an...
