Abstract
This paper presents a numerical study of the effect nanofluids on the erosion corrosion in the pipes by using coolant fluids. One type of nanoparticles used in this paper cupper (Cu) and the base fluid (distilled water) as well as the nanoparticles size used are ranging from (20 – 50 nm). The concentrations of nanofluid used are ranging from (1 – 3 vol %). The results indicated that property of nanoparticles and their effects on the behavior of the erosion and corrosion due to the cavitation phenomenon, which causes pipe wall erosion. This study reveal the effect of the nanoparticles concentration on the flow phenomenon. Furthermore, the type and size nanoparticles play an important role in the nanofluid flow, thermall properties and erosion – corrosion behavior. The obtained results indicated that the contribution of the temperature enhancement and the velocity of nanofluids on the radiator shape, design and materials. Results showed the critical pressure distribution along the flow field and predictions on effect of temperature during the erosion – corrosion process. Moreover the results indicated the effect of velocity, temperature and thermo physical properties on on the erosion corrosion in the pipe. Two the flow condition used in this study laminar and turbulent
