Abstract (English): The present paper aims to present the analysis and comparison of results of computational simulations using Computational Fluids Dynamics (CFD) in impellers of centrifugal pump. Tree impellers were simulated: 1) original impeller, 2) original impeller with splitter blades at outlet; 3) original impeller with splitter blades at inlet. The splitters occupied 30% of the length of the main blades. They were simulated using the ANSYS-CFX software system in 1500 rpm rotational speed and at different flow rates. The turbulence model assumed was the Shear Stress Transport (SST). The results were used to build impeller blade head curves, besides the presentation of pressure distribution and streamline behaviour inside the impeller. It was verified that the insertion of the splitter blades reduced the impeller blade head, mainly the impeller with outlet splitter, whose reduction was more intense. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): A proposta deste artigo é apresentar a análise e comparação dos resultados de simulação computacional usando a Dinâmica dos Fluidos Computacional (CFD) em rotores de bomba centrífuga. Três rotores foram simulados: 1) rotor original; 2) rotor original com pás intermediárias na saída; 3) rotor original com pás intermediárias na entrada. O comprimento das pás intermediárias foi de 30% do comprimento da pá principal. Eles foram simulados usando o software ANSYS-CFX na rotação de 1500 rpm para diferentes vazões. O modelo de turbulência adotado foi o Shear Stress Transport (SST). Com os resultados foram construídas as curvas de altura produzida pelas pás do rotor, além da apresentação da distribuição de pressão e comportamento das linhas de corrente dentro do rotor. Foi verifcado que a inserção das pás intermediárias levou à redução da altura produzida pelas pás do rotor, principalmente para o rotor com pás intermediárias na saída, na qual a redução foi maior.
