A dynamic model, describing the time evolution of a stellar wind and its associated HII region, was developed. A system of nonlinear, ordinary differential equations and algebraic equations which can be numerically integrated without large computer time was deduced. Model calculations show that the time evolution has to be divided into three phases. An equation for the motion of an ionization front in the first two phases was deduced. The interaction between ionization front and shock front, occurring at the end of the second phase, was treated as a Riemann problem. The effect of dust on the dynamics of HII regions is found to be largest for high gas densities. The cooling of the shocked hot wind region was determined. The proposed model allows the determination of the flow structure in the neighborhood of young stars, and other astrophysical flows with discontinuities.
