根据Vesovic-Wakeham理论,预测了10种HFC类二元混合制冷剂的气相黏度,所研究的混合制冷剂包括R32/R125、R32/R134a、R32/R143a、R32/R152a、R125/R134a、R125/R143a、R125/R152a、R134a/R143a、R134a/R152a和R143a/R152a,温度范围为298.15~423.15 K,压力范围为0.1~8.85 MPa,结果表明,黏度预测值具有较高的精度,可以满足工程应用的实际要求。
The gaseous viscosity of binary HFC refrigerant mixtures was predicted by Vesovic-Wakeham theory for the temperature ranges from 298.15 K to 423.15 K and at pressures up to 8.85 MPa.The studied binary mixtures are R32/R125,R32/R134a,R32/R143a.R32/R152a,R125 /R134a.R125/R143a.R125/R152a.R134a/R143a,R134a/R152a and R143a/R152a.The theoretically calculated results for the viscosity were in close agreements with the experimental data.
