Blood flow simulations by equivalent transmission line models: from fluid dynamics to distributed circuit theory.

The simulation of the blood flow propagation in the human cardiovascular system has received a lot of attention in different research communities. A variety of simulation techniques have been developed over the years considering the solution of fluid dynamics equations. Most of these techniques are very computationally expensive.


The objective of this project is to investigate and test the accuracy and efficiency of transmission line models to represent the blood flow propagation in the human cardiovascular system [1],[2]. This will allow using circuit solver simulators (e.g., SPICE) and/or solvers for (delayed) differential equations instead of computationally expensive fluid dynamics simulators. A very significant speed-up will be achieved while preserving accuracy. Different physiological and pathological (e.g., artery occlusion) conditions can be analyzed.

The code for modeling and simulation is going to be implemented in Matlab.
