We present a 2D-hydrodynamical simulation of the gas flow generated by a starburst in a dwarf galaxy. We focus in particular on the ejection efficiency both of the ISM and of the metals produced during the burst. It turns out that while the galaxy is able to retain most of the ISM, a significant fraction of the metals is lost, supporting the differential wind scenario. A new burst may occur after ∼ 0.5-1 Gyr, when the central gas surface density approaches the critical value, during the post starburst gas replenishment.
