Outline of Final Research Achievements

I have visualized blood flow from the left ventricle to the aorta and researched the pressure change in them with the simulation model generated from a real patient CT data.
In the model generation, data reduction and addition of dummy particles for prevention of outflow particle have been performed. In addition, Navier-Stokes equation and Cauchy-Navier equation are derived from Cauchy equation of motion by applying constitutive equations of liquid and elastic body for the behavior analysis of them, so that it has become easier to analyze the interaction between them.
As the result of the simulation, the aortic valve has opened according to the pressure ascension in the left ventricle, and the blood flow into the aorta has been observed. By the comparison of the simulation result with pressure change in a medical book, I have confirmed that the pressure change in the left ventricle was similar to the data in the book.
