Samara Scientists Create a Digital Dynamic Model of Cardiovascular System

Researchers work within the framework of Samara Polytech interdisciplinary project team

Dmitry Pashchenko, Candidate of Technical Sciences, Assistant Professor of the Industrial Heat-and-Power Engineering Department is the head of the project. From the computer engineering and computational fluid dynamics point of view, the heart is a membrane pump, the vessels are flexible conduits, and the blood is an incompressible non-Newtonian fluid.

Ideally, the model should be simple and accessible so that everyone can launch an application on a smartphone and download the results of electrocardiography, see a digital analogue of their cardiovascular system. The consultants and experts on medical issues from the Center for Cardiovascular Surgery named after A.N. Bakulev and Samara branch of the University «Reaviz» are involved in the team work.

Dmitry Pashchenko hopes that successful implementation of the idea will allow to integrate the model into one of the telemedicine services like «Yandex. Health».

«The members of the interdisciplinary project team «Computer Engineering and Digital Production» Samara Polytech students Ilya Naplekov, Ivan Zheleznikov and other participants developed the calculated geometry of a human heart and made its discretization with the imposition of a grid,» - says Dmitry Pashchenko. He adds that one of the main steps in creating a digital double is actually passed. Then they will adapt the geometry and try to bring it as close as possible to the real structure. The next stage will be «reviving» the geometry by using CFD modeling, verifying the results using experimental data and visualizing the results.

Young scientists are also working on several tasks from related fields of science and technology. For example, members of the interdisciplinary team develop a digital model of the dispersion of combustion products from the flue pipes and a methodology for assessing the impact of these emissions on nearby residential buildings.
