Description
The purpose of this project is to synthesize a CFD model which can explore the nature of vortices induced by alternating magnetic currents within colloid rollers. This type of research has been a point of interest in previous years especially for the application of targeted drug delivery. This research hopes to further establish and quantify the dynamics of these fluids in order to provide more numerical data for BioMed applications. In order to accomplish this, a simplified model of a Ginzburg Landau model (A coupled PDE solver) was created within the program Python in order to test the parameters of the system. This testing varied parameters such as the alternating current frequency, viscosity of the intermediary fluid, colloid particle density and particle size. From current literature, the frequency is expected to induce periodic behavior particularly in the mode of density bands, vortices, and fluctuations/swarms. Several struggles have appeared with the intermediary testing of our solver including numerical instability or trivial solutions which are typical problems for these types of models. In addition to the Python model, a 2D CFD model was constructed within Ansys Fluent in order to visualize the behaviors emerging from the system and come to a more concrete correlation in regard to the tested parameters. This CFD model also provides an additional method for validation against our python solver which may help us move past the previously stated issues. If this research is supported, further validation and sensitivity analysis (testing over a wide range of parameters in order to find an optimum range for stability) could be conducted on our present model.
