Introduction

Our research at the Hemodynamics Lab mainly focuses on understanding the blood flow through cerebral aneurysms and characterizing the hemodynamic parameters associated with aneurysm formation, growth and rupture. This study is carried out by utilizing diverse approaches such as Mathematical and Computational (CFD) Modeling, Fluid-Structure Interaction (FSI) analysis, Stereoscopic Particle Image Velocimetry (SPIV) measurements and Digital Subtraction Angiograpgy (DSA) images. The ultimate goal of this work is to come up with patient-specific and better treatment paradigms, which will prevent aneurysm growth and consequent rupture. The effectiveness of stenting in reducing the intra-aneurysmal flow as well as use of natural emboli for aneurysm occlusion are being investigated in this regard.

The computational resources for CFD and FSI analyses are provided by the Center for Computational Research (CCR) and Science and Engineering Node Services (SENS), SUNY, Buffalo. These analyses are carried out using commercially available softwares such as ProE, ICEMCFD, STARCD and Tecplot. Such resources help calculate different hemodynamic parameters and better visualize the overall blood flow pattern, which are key factors for this research work.

The Hemodynamics Laboratory environment nourishes tomorrow's scientists with new insights into the understanding of a great remaining fundamental challenge to scientists and engineers: turbulent flow phenomena. The LFD research team is continually searching beyond the limitations of existing knowledge, challenging the frontiers of turbulence research by combining state-of-the-art optical diagnostics techniques with physics, theory, experiments, and latest computation/visualization tools. By fostering creative independent thinking in a stimulating new research field, our students gain invaluable wisdom and experiences, which provide a distinct advantage for all their future endeavors.
