There have been a few attempts to combine chemical and dynamical evolution models for dwarf galaxies of various types. ... Our approach follows naturally from the evidence that supernova explosions (SNe) and superbubbles (SB) are the main contributors to the galaxy energy budget, and are easily able to regulate the its metal content. ... The amount of mass and metals lost in an outflow is regulated by the pressure in the ISM, which in turn depends upon the amount of energy injected by previous SNe. ...
