Title in Portuguese
Campos de velocidade e pressão através de uma hemo-bomba de parafuso micro-axial.
Keywords in Portuguese
Bombas axiais
Equações de Navier-Stokes
Abstract in Portuguese
A solução numérica das equações incompressíveis de Navier-Stokes através de uma bomba axial foi determinada gerando diagramas dos campos de pressão e velocidade. Utilizou-se o método dos volumes finitos implementado com um sistema de referência giratório. Um modelo laminar foi usado para modelar o fluxo como o de um fluido Newtoniano, simulando as características da água através de uma bomba de sangue micro-axial. O modelo exibiu resultados razoáveis de acordo com os princípios de bombeamento axial. Uma investigação experimental foi conduzida para obter dados de pressão ao longo da parede interior da bomba. Os resultados numéricos e os dados experimentais foram avaliados a fim de aprimorar as técnicas de desenvolvimento de modelos numéricos que permitam prever o desempenho de modificações na bomba original.

Navier-Stokes equations
Abstract in English
A numeric solution to the incompressible Navier-Stokes equations across an axial pump, has been found. Images of pressure and velocity fields across the impeller were generated applying computational fluid dynamics methods. The finite volume method was integrated with a technique which employed a moving reference frame. A laminar model was used to model the flow as a Newtonian fluid imposing the characteristics of water across the impeller of a micro-axial hemo-pump. The model exhibited reasonable results in agreement with axial pumping principles. An experimental investigation was conducted to obtain pressure values along the inside wall of the pump housing. Numerical results and experimental data are evaluated to allow refinement of development techniques and generate modifications to the original pump.
