Conversion of mechanical energy into pressure inside a fluid -or inversely-, is necessary in numerous industries: transport, electricity production, air circulation... Rotating machineries are often used in these frames. They are constituted of at least one bladed rotating part giving energy to the fluid (the impeller) and connected to a shaft, which is entrained by a motor in the case of a pump. The design method of such turbomachines has evolved from the begining of the last century to these days. Nowadays Computational Flow Dynamics (CFD) local scale computations are used to optimize the pump components. Local simulation allows to obtain information on what is happening inside the machine in three dimensions. However, qualification of th...
