摘要: We investigate the weakly nonlinear stability theory of a thin micropolar liquid film flowing down along outside surface vertical cylinder. The long-wave perturbation method is employed to solve for generalized kinematic equations with free interface. normal mode approach first used compute linear solution flow. multiple scales then obtain weak dynamics flow analysis
