The evolution of a massive binary system consisting of a 40- and 25-solar mass star has been studied in the conservative and nonconservative approximation in mass transfer phases, Case A and Case B. Specific attention is focused on the differences between the evolutions when account is taken of the enhancement of a stellar wind associated with tidal effects and irradiation. For the form of the mass loss formula adopted, only tidal effects were found to be important. The effect is significant in Case A, but not in Case B. The relation between mass and angular momentum loss is discussed.
