This paper uses different CFD solvers to verify the laminar flow problem. Verify the accuracy of each solver by listing the operating procedures and differences in the output results of different solvers.

1. Problem description

As shown in the figure below, a fixed-constant laminar flow model between two concentric cylinders is established. The flow is caused by the rotation of the inner cylinder at a constant angular velocity, while the outer cylinder remains stationary. Using periodic boundaries, only a portion of the basin needs to be modeled. The physical model and input data are shown in the following table.
