Scientific paper

In a radiatively driven wind model, the dynamical effect of turbulence is included. Models are calculated for core hydrogen burning stars, luminous blue variables and a Wolf-Rayet star. For all these models the addition of turbulence either has little effect or else leads to a large temperature increase which is contrary to observational evidence. Turbulence therefore cannot explain the discrepancies between the observed and theoretical terminal velocities for O-type stars. Neither can it explain the large mass loss rates observed in luminous blue variables (during their eruptive phase) or Wolf-Rayet stars.
