Abstract: The paper introduces a new concept in sheet metal forming, which is multichannel sheet hydroforming technology. The new con cept assures an improving of the flexibility of the hydroforming technology as well as an increasing of the productivity. This concept is based on the use of a high fluid pressure that is transmitted through a number of channels to the same number of defor mation cells. The experimental and numerical results validate the new technology concept.

Abstract: A three dimensional numerical study of flow characterized of fly ash - water slurry in a horizontal 180 ̊ pipe bend having radius ratio of 5 .6 is described in this paper. The flow constitutes the fly ash particles of size 13 μm in water at velocities ranging between 1.0 - 5.0 m/s and particle concentrations ranging between 10 - 50% by volume for each velocity of flow. The numerical simulation is c arried out by deploying the Eulerian Multiphase Model of CFD code in ANSYS Fluent code. The results illustrate that the overall pressure drop is 62% in the pipe bend at all particle velocities and concentrations. The velocity and concentration distribution s at various positions (0 ̊, 90 ̊ and 180 ̊) of the bend were illustrated.
