Experimental and Numerical Investigation of Al2O3 Nanofluids Based Crude Oil in Shell and Tube Heat Exchanger
Numerical investigation of heat transfer augmentation with Al2O3 nanofluids-based crude oil in a shell and tube heat exchanger. This paper presents numerical and experimental investigations to study the effect of using Al2O3 nanofluids based crude oil on heat transfer enhancement in a turbulent regime with mass flow rate of (4 to 18 kg/s) in the shell and tube heat exchanger. The investigation concentrates on the effects of the Al2O3 based crude oil nanofluids on friction factor, flow characteristics and heat transfer, through shell and tube heat exchanger. The results show that the thermal conductivity as well as the viscosity of Al2O3 nanofluid based crude oil increased with increasing nanoparticles volume fraction and decreased with increasing the temperature. The outcomes revealed that the Nusselt number improved with increasing mass flow rate and also the friction factor increases dramatically using nanofluid this because of increment in nanofluid viscosity comparing to the base fluid (crude oil), additionally the results illustrate a constant pattern along the heat exchanger.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
