Abstract
We investigate the peculiar velocity field due to long cosmic strings in several cosmological models and analyze the influence of a nonscaling behavior of the string network, which is expected in open cosmological models or models with a cosmological constant. It is shown that the deviation of the probability distribution of the peculiar velocity field from the normal distribution is only weak in all models. It is further argued that one cannot necessarily obtain the parameter b5V0 0.6/b from density and velocity fields, where V0 is the density parameter and b the linear biasing parameter, if cosmic strings are responsible for structure formation in the universe. An explanation for this finding is given.
