Abstract:
Using the dimension reduction procedure, one-dimensional model of the periodic blood flow in the artery, which flows out through a small hole in the thin elastic artery wall connected to a spindle-shaped hematoma, is constructed. This model is described by a system of two parabolic and one hyperbolic equations provided with mixed boundary and periodicity conditions. The blood exchange between the artery and the hematoma is expressed by the Kirchhoff matching conditions. Despite the simplicity, the constructed model allows us to describe a damping of pulsating blood flow by the hematoma and determine the conditions of its growth. In medicine, considered biological object is called a false aneurysm.
Key words and phrases:
circulatory system, aneurysm, hematoma, blood vessel, dimension reduction, Reynolds equation.
