Abstract
A smoothed particle hydrodynamics numerical model is described and tested for the discharge of healing agent within a self-healing composite structure. As an initial validation of the model, discharge for low Reynolds number flow from a cylindrical tank is simulated and results compared to existing experimental data. The method shows good agreement for Re <20, predicting the discharge coefficient to be given by 0:154Re0.471, compared to the experimentally known result of 0:142Re0.504. Further comparison reveals the importance of ensuring good resolution of the discharge flow in order to recover the high Re limit case, and that two different numerical viscosity formulations in this instance give very similar results.
