Volute flow in radial flow centrifugal pumps study. Theoretical and experimental study
Abstract
An analysis was made of the flow of water within the volute fed by the impeller of a centrifugal pump, without recourse to uniform pressure hypothesis, yet with one-dimensional theory. To go beyond the limits peculiar to such simplified approach, experimental tests were performed to evaluate radial thrust on the impeller and direct measurements were made of the pressure distribution in the volute casing. Information on fluid flow patterns (based on relative momentum variations) were obtained which are needed for further refinements of the theory.
