The use of centrifugal pumps in the hydraulic transport of nano-fluids poses major problems for the rational choice of the type of pump capable of working with a nanoparticle concentration difference in a base fluid . In this context, the objective of this work is to study the internal flow in an inter blading canal of a centrifugal pump for pumping fluid nano Al2O3/water to various concentrations. And this through the ANSYS - CFX software, based on the finite volume method. The turbulence of the flow in the inter-blade canal is taken into account using the k-ɛ model. The results obtained show that the addition of nanoparticles in the nano fluid has an appreciable effect on the flow velocity, pressure and shear stresses.
