Application of the modernized jet flow model to calculate the movement of physiological fluids in the living body

To describe the movement of physiological fluids in the body, in some cases it is possible to use a jet flow model. For example, the movement of blood from the capillary into a vein or artery. The geometric scheme of motion is the Union of a small section channel with a camera of significantly larger dimensions. The paper considers the applicability of the flooded jet model. The results of the calculation of the velocities based on models that allow an analytical solution, namely, the first and second approximation of the jet flow, are compared with the results of the numerical solution of the Navier-Stokes equation by the finite element method using the COMSOL MULTIPHYSICS software package. The idea of adjusting the jet parameter based on the results of taking into account the additional component of the impulse flow is discussed.
