“…The ability of the model to predict reliably the pump performance in steady operation has been proven in a previous work (Matteo et al [8,9]). The objective of the present work is to extend the work to transient operations.…”

“…Several slip factor correlations have been implemented in the 1D pump model in order to make sensitivity studies and evaluate qualities and defaults of each (those of Stodola [32], Stanitz [33], Wiesner [34] and Qiu [35] as well as the one developed in the frame of this project). These correlations have been tested on four centrifugal pumps, two mixed flow pumps and one radial compressor (Matteo et al [8][9][10][11][12][13]). The correlations are described here after.…”

“…The maximal relative error is reached at a very low flow rate close to 30%Q N . The strengths of the model are, first, to ensure such an order of error for very different geometries from radial to mixed flow machines (10 < N q < 120) and from little to very large components (20 cm < D impeller < 150 cm), and, second, to predict these presented performance curves with a very low computation cost (6 s on one core of a standard computer) (see Matteo et al [9][10][11][12][13]). Probabilistic studies can complete such a model by changing randomly parameters of the model and analysing the impact of uncertainties on the final results.…”

“…This traditional model is not predictive and cannot be used for Generation IV two-phase flow applications. For this reason, it was decided to implement a predictive transient, two-phase flow rotodynamic pump model in the CATHARE code and qualify results at component scale (pump) and system scale (reactor) with respect to available experimental data (Matteo et al [8][9][10][11][12][13]). The global strategy of the CATHARE-3 one-dimensional pump model development project and the first pump-scale verification and validation results were presented by Matteo et al [8,9].…”

A predictive transient two-phase flow rotodynamic pump model has been developed in the Code for Analysis of THermalhydraulics during an Accident of Reactor and safety Evaluation (CATHARE-3). Flow inside parts of the pump (suction, impeller, diffuser and volute) is computed according to a one-dimensional discretisation following a mean flow path. Transient governing equations of the model are solved using an implicit resolution method and integrated along the curvilinear abscissa of the element. This model has been previously qualified at the component scale by comparison to an existing experimental database. The present study aims at extending the validation at the system scale: a whole experimental test loop is modelled. The ability of the transient pump model to predict flow rate, head and torque as a function of time during a 1-s pump fast start-up is evaluated. The transient evolution of the pressure upstream and downstream from the centrifugal pump is well predicted by the simulation compared to the measurements. Local quantities such as pressure and velocity inside elements of the circuit are analysed. In the considered case, inertial effects of the global circuit are dominant when compared to pump inertial effects due to the high characteristic lengths of the pipes. The main perspective of this work consists in the simulation of similar pump transients, in cavitating conditions.

“…However, due to some limitations when experimental facilities are not satisfactory, the analytical method can be used to minimize experimental work to verify the results obtained from other techniques [31]. Such model verification was made by mathematically comparing the simulation result with analytical results, as introduced in the literature [32][33][34], to prove the applicability of the CFD model implementation. As shown in Figures 4 and 5, the CFD results in different operating conditions were compared with the corresponding theoretical data.…”

Numerical Research of Pump-as-Turbine Performance with Synergy Analysis

The wide use of pumps and turbines has significant value in energy conservation and utilization. In this work, a three-dimensional Computational Fluid Dynamics (CFD) model and a one-dimensional theoretical model of a Pump as Turbine (PAT) were established. On this basis, the correlation between pressure and velocity was quantitatively investigated by a proposed sensitivity index (SPV). A synergy field analysis was then applied to evaluate the flow characteristics of a pump and PAT, providing a perspective from the mechanism of the energy transfer enhancement for hydraulic devices. Moreover, the hydraulic and synergy performances of PAT were studied under various operating conditions. The results show that the minimum SPV is obtained in the impeller. With increasing flow rate, the SPV of the PAT generally increases, and the synergy angle of the impeller surface increases as well. A strong disordered synergy field is observed in regions of the blade leading edge, trailing edge, and volute tongue. The variations in efficiency and head with flow rate showed similar trends, respectively, with the synergy angle of the outlet and the mid-plane. This study provides an analytical method for quantitative evaluation of flow synergy characteristics, and it supplies a basis for further design improvement of the pump and PAT.
