Welcome
Welcome to the the Multiphase and Cardiovascular Flow
Lab at the University of Washington.
We are a Fluid Mechanics Laboratory focused on understanding
the fundamental physics of Mutlphase Flows and the role of
fluids in the human cardiovascular system. We perform
experiments, numerical simulations and theoretical analysis to
improve understanding of the Fluid Mechanics, as well as to
solve fundamental
problems in Medicine, Energy, and Environmental Engineering.
Some problems we are working on right now are:
- Hemodynamics in Intracranial Aneurysms, specifically after
treatment with endovascular stents and coils.
- Fluid Mechanics of Mechanical Circulatory Support in
Cardiology, specifically the understanding and reduction of
the risk of thrombosis in Left Ventricular Assist Devices (a
pump implanted to support the left ventricle in advanced Heart
Failure patients).
- Hemodynamics of Pediatric Congenital Heart Disease,
specifically the design and modeling of surgical patches for
repair of aortic coarctation.
- The use of Doppler Ultrasound in understanding the Fluid
Mechanics of blood flow in the human body, and diagnosing
cardiovascular disease, specifically the use of Transcranial
Doppler to understand blood flow in the Circle of Willis (a
complex manifold that provides redundant flow of blood to the
brain) in health and under vasospasm (a very serious condition
where one or more of the vessels that bring blood to the brain
are suddenly and severely contracted).
- The Dynamics of Inertial Particles in Turbulence,
specifically the trajectories and collisions of water
microdroplets in clouds, leading to the process of Warm Rain
formation.
- Atomization and Sprays. The process of Break-Up of a Liquid
Jet by a High-Speed Gas Jet and the distribution of the
resultant liquid Droplets in Turbulent Multiphase Flow.
Specifically, the Sensing and Control of this process that has
many applications in Nature (Sea Spray, Hydrothermal Vents,
etc.) and Engineering (liquid Fuel Injection in Gas Turbines,
Jet Engines and Rocket Engines, Additive Manufacturing, Spray
Cooling, Pharmaceutical Oral Dose Manufacturing, etc.).
