Fluid Flow in Tube with Obstacle: the New Calculation Method and the MATLAB-program

In Fluid Flow in Tube with Obstacle, the author describes how to calculate the fluid flow in a tube with an obstacle by calculating the velocity and pressure of the liquid at all points of the tube. In the variational principle of the extremum, a viscous incompressible and compressible fluid is proposed, followed by the notion that the Navier-Stokes equations are the conditions for the unique extremum of a certain functional. A method is also proposed for the search for this extremum, which is simultaneously a method for solving these equations.

MATLAB is used to solve numerous examples in the book.
