摘　　要：In this paper a numerical method for understanding the flow pattern and calculating the available torque in a single axis subsystem version of advanced inertial reference sphere was provided. The governing equations were parabolized in stream-wise direction. The SIMPLEC algorithm coupled with an algebraic second-moment closure of turbulence was applied to solving the equations. Computational results were compared with measurements.In this paper a numerical method for understanding the flow pattern and calculating the available torque in a single axis subsystem version of advanced inertial reference sphere was provided.
