Numerical Study of Condenser with Nano-Fluids to Improve the Thermo- Physical Property

Abstract

The CFD analysis has been carried out for
three refrigerant R134a, cubic and spherical
shape Al2O3/R-134a refrigerant for three
various inlet temperatures 310K, 315K, and
320K correspondingly at constant cold and
hot fluid mass flow rate. The outcome shows
that in all conditions the overall heat transfer
coefficient (U) is higher for R134a cubic shape
Al2O3/R-134a Nano-refrigerant and it is
reduced following the R134a spherical shape
Al2O3/R-134a Nano-refrigerant and at last
the R134a refrigerant. The maximum cooling
can be achieved by using R134a cubic shape
Al2O3/R-134a Nano-refrigerant. The cooling

accomplished by R134a cubic shape Al2O3/R-
134a Nano-refrigerant is more in percent for

instance about 92.53% look at then R134a
and 24.06% then R134a round shape
Al2O3/R-134a Nano-refrigerant at 320K hot
liquid channel temperature separately.
