| Abstract: | It has been difficult to predict performances of mixed flow pump at low discharge because of difficulty in theoretical treatment of recirculation flow at impeller inlet and outlet. The present study proposes a new method predicting pump overall performances in wide discharge range by introducing an appropriate recirculation flow model at an impeller inlet into quasi-three-dimensional flow calculation and by determining hydraulic loss analysis. Comparison with measured data revealed that the present method gives fairly good prediction to pump performance curves.
La difficulté à analyser théoriquement l'écoulement inverse à l'entrée et à la sortie d'une roue de pompe hélico-centrifuge a longtemps rendu délicate la prévision des performances d'une roue de pompe à faible débit. Cette étude propose une nouvelle méthode pour prédire les performances générales d'une pompe dans un vaste domaine de puissance, en introduisant un modèle approprié de l'écoulement inverse à l'entrée de la roue et en déterminant le comportement du facteur de glissement à sa sortie. La comparaison avec de nombreuses données expérimentales a montré que cette méthode permet une prédiction réellement bonne des courbes de performance de la pompe. |
