摘要：
We obtain three models for geodesic flows and three models for non-geodesic flows of Weyssenhoff fluid considering it as the source of gravitation and spin in the Einstein-Cartan field equations. Influence of spin on the pressure, density, equation of state, and the kinematical parameters is observed in both geodesic and non-geodesic models.
