Abstract
In our research, we have analyzed a propagation of pulse inside a collapsible tube, which could be seen inside an artery of human body. Flow inside collapsible tube is basically analyzed using continuity equation, NS equation and equilibrium of force on tube walls. In the process of analytical solution with perturbation method, these equations could be transferred into a KdV equation, which is known for producing solitary wave. Analytic solution and its form are derived.
