Modeling Leakage Flow from External Gear Pumps

One issue with using external gear pumps in fluid power is the leakage produced from the pumps. This issue is further compounded because based on the tolerances a company uses to manufacture the pump, estimating the leakage accurately can become a difficult task to achieve since the amount of leakage depends on these tolerances. My research mainly focuses on writing MATLAB code and running simulations to estimate the leakage as a function of the tolerances provided to us. In the future, we would like to experiment with pumps to see if our simulation data holds up in real world experiments.
