Velocity and concentration distribution in slurry pipe flow O.A. El Masry, M.M. El Halawany Mechanical Engineering Department, Faculty of Engineering, Alexandria University, Alexandria ABSTRACT This paper presents theoretical analysis and experimental verification of the velocity and concentration fields in a low concentration steady slurry turbulent flow in a horizontal pipe. The velocity distribution was obtained by the integration of the linear momentum equation. The velocity gradient was considered as the result of the gravitational force, hindered turbulent motion, concentration distribution of the solid particles and mixing effects due to the interaction of the liquid and the solid particles. The obtained explicit algorithm does not require system of equations to be solved. An experiment was designed and carried out to test the theoretical model. Using sand-water suspension of up to 10% solid concentration and an average velocity of up to 2.4 m/s in a 18.35 m length an
