Abstract: Design and analysis of diffuser/nozzle micropump using ANSYS-FLUENT is attempted for fuel delivery in automobile. To enhance the performance of the micropump a historic dimensional design such as the diffuser length, the diffuser angle, and the throat/neck width of diffuser/nozzle elements are obtained from the simulation results. The fluid velocity of the diffuer/nozzle and the pressure loss rates are calculated. The simulation result shows that there is an optimal dimension of the diffuser/nozzle to obtain a large flow rate and to minimize the velocity and the pressure losses.

 

Keywords: ANSYS-FLUENT, Diffuser/nozzle micropump, Diffuser angle
