Blood Flow Simulation Based on Electrical Network Theory and Computational Fluid Dynamics
The upper extremity arteries of the human body include the brachial artery and the radial artery.These two arteries are often used as the key parts for measuring human blood pressure and pulse wave,reflecting a lot physi-ological and pathological information.We compare and combine the electrical network model method based on the e-lastic cavity and the bidirectional fluid-structure coupling computational fluid dynamics model method.To study the hemodynamics of the upper limb arterial segment in the human body in the healthy and atherosclerotic state,two simu-lation models under the same structural and mechanical parameters are established.On the one hand,the arterial pulse wave is dynamically simulated through the electrical network model,and it is found that the main wave peak of the pulse wave under atherosclerosis has obvious rise and lag.On the other hand,by the the bidirectional fluid-struc-ture coupling computational fluid dynamics method,we analyze the local mechanical properties of the blood flow field such as velocity,pressure,so as to provide references for the formation and prediction of atherosclerosis and other car-diovascular diseases.
