Abstract
Oil pump in diesel engine has significant effect on energy consumption and environment pollution. In this
paper, the modeling and simulation of a gear oil pump used in a diesel engine and its fluid flow analysis by
a solver has been explained. Also the optimization and redesign of it has been discussed and then the
outcomes have been compared with the experimental and previous results. The type of this oil pump is
external gear pump with involute tooth profile, so we need to use the gears with the minimum number of
tooth to optimize the pump performance and getting the optimum displacement volume rate of it. While the
engaged gears of the pump rotating together, the intersection between them changes in time. So their
boundaries should be considered as movable. The strategy used here consist in using dynamic meshes,
dividing a tooth rotating cycle into a certain number of time steps and investigating the flow and getting the
results for each time steps.
