Numerical Simulation of electrically conducting fluid flow Using OpenFOAM

Introduction:
Aortic dissection is a cardiovascular disease with high mortality. When it comes to diagnosis, impedance cardiography is a standard method to monitor a patient’s heart function and circulatory system by injecting electric currents and measuring voltage drops between electrode pairs attached to the human body. If such measurements distinguished healthy from dissected aortas, one could improve clinical procedures. Therefore, computational modelling of blood-flow-induced changes in blood electrical conductivity is of great importance and could contribute to better assessment of impedance cardiogram.

Aims:
The main goal of this thesis is to investigate the applicability of OpenFOAM software for numerical simulations of blood flow as a conducting fluid flow, which eventually could be used for impendence cardiography method in case of Aortic dissection.

Description:
Currently, in OpenFOAM, Maxwell equations coupled with Navier-Stokes equations are implemented. The tutorial case in OpenFOAM considers a problem which is known as the Hartmann problem defined as follows:


Geometry and Boundary Conditions

In this example, the flow of an electrically conducting liquid through a magnetic field is simulated using the mhdFoam solver in OpenFOAM.

 Tasks:
•    Simulating the tutorial case in OpenFOAM and understanding of the simulation results.
•    Simulating a new case, including the voltage equation. Currently, the equation for computing voltage is not present in the software, which could be derived from maxwell equations and added to the code.

Requirements:
Familiar with finite volume discretization method.
