Development of an app for fluid dynamics simulations in small and large vessels

2020 
The rheological properties of the blood depend on numerous factors among which the geometry and the size of the conduit in which the blood circulates. The human body is made up by vessels having a different structure and characteristics, which depend on the function they perform, above all on the pressure they have to bear generated at the cardiac level. So, a great criticality when approaching a study on blood flow behavior in the circulatory system is to use an appropriate mathematical model for the circulating fluid. Though the CFD analysis (computational fluid dynamics), going to investigate what are the differences produced by the use of models in the study of vessels of different caliber can be a valid support in the study of vessel fluid dynamics, in particular if they are affected by pathologies. In this regard, the aim of this work, is through the implementation of an application, to carry out a statistical analysis of the effects of different blood flow models in arteries to identifying a prediction about the percentage variation of the shear stress indices involved in the impact of atherosclerotic plaque.
