Comparison of different method for calculation of velocity field in centrifugal pump impeller
Trnčík, Tino ; Bezdíček, Jiří (oponent) ; Štefan, David (vedoucí práce)
This master´s thesis deals with the design of impeller of radial centrifugal pump from the point of view of prediction of velocity field in meridional plane. To achieve this, a software combining potential flow method with Francis’s method of velocity field prediction was used. This results to 6 designs, which represent both methods and simultaneously a combination of both. Also, an own design is proposed using basic empirical relations. All this design proposals are then compared with each other and with original geometry of radial pump with n_s=135,36 min^(-1).When evaluating results, greatest emphasis is placed on comparison of predicted velocity field with the one obtained by using CFD simulations. And how well the prediction stacks up to the simulations and how the finite number of blades, their thickness and other factors affects resulting velocity field.
