Instrumentation for an array of research applications
In 一个 of 菠菜网lol正规平台’s most significant instrumentation acquisitions to date, Alessandro Bellofiore led the College of 工程’s procurement of a High-Speed Particle Image Velocimetry (PIV) instrument, a laser-based tool for characterizing flow fields. 有 this instrument on campus will advance faculty and student research relating to fluid mechanics in biomedical devices, microscopic blood cell interactions, ink technology droplet mobility, aerodynamic and combustion evaluations, and more.
“Particle image velocimetry is a powerful and reliable tool for characterizing flow
in a wide array of applications,” explains Bellofiore (at right). “这是事实
standard for the experimental investigation of liquid, gaseous, and multiphase flows,
whether 一个 is investigating fuel injection processes in aircraft engines or blood
flow through implantable cardiovascular devices.”
Using the PIV instrument, Bellofiore and his students are conducting research on the blood flow patterns associated with mechanical heart valves. 创建了模拟之后 circulation loop that mimics the vascular system, they apply a thin sheet of laser light to illuminate a slice of a flow that is seeded with highly-reflective particles, and use a high-speed camera to take images of the particles. 复杂的软件 analyzes the images to quantify how much each cluster of particles moves, which in turn gives a measure of the fluid flow velocity.
Bellofiore’s passion for fluid dynamics was sparked when he was a student in Italy. “It was definitely the combustion course I took at University of Naples Federico II. It introduced me to the wonderful world of fluid dynamics, and motivated me to choose to focus on experimental fluid mechanics throughout my career.”
“My experience at 菠菜网lol正规平台 has been great.
I love how the professors involve the students in research.”哈尼亚奥斯曼
