| We have used Acoustic Emission (AE) methods to study the pulsatile flow of Non-Newtonian fluids in porous media. Our efforts have been directed in defining the problem, identifying the objectives and detailing an experimental approach through the use of AE principles with the assistance of a Vibration Assisted Liquid Composite Molding Apparatus to solve the problem. We have investigated the phenomenon of pulsatile flow of non-Newtonian fluids as they flow in a porous medium which can be applied in a stenosis medium such as the artery. In achieving these objectives, our research has included experiments, analysis, and computational modeling. The diagnosis of vascular diseases has been of great interest not only to researchers and biomedical professionals but it is a dilemma that affects a large segment of the human population, and it is one of the greatest challenges that patients, their loved ones and their doctors grapple with on a daily basis.;This research will hopefully shed more light not only on the understanding of vascular diseases, but its development and the progression of aneurysm and atherosclerosis. Some researchers using other methods that have been reviewed in the literature survey have provided very promising results by tackling this problem but there is still a lot to be done. We have applied the techniques of NDE with particular focus on Acoustic Emissions (AE) techniques to analyze the above. NDE applications have been used in several engineering disciplines and in most cases have achieved very promising results.;This research is also applicable to other areas of engineering. An important example is the flow of non-Newtonian plastic and polymer melts and some liquid metals in the molding and casting processes.;Based on the above, we hope that this research will have great potential both in the medical and industrial applications. |
