Experimental and numerical model to determine the feasibility of using acoustic pulses to detect catheter occlusions
(2011)
The purpose of this research is to determine the capability of detecting central venous catheters occlusions by using guided acoustic waves in a fluid filled tube. The pulse sent through the fluid will be reflected if the ...
An experimental study of bubble parameters in subcooled flow boiling in vertical channel to validate different heat flux partitioning models
(2019-05-10)
Pressurized water reactors (PWR) are safely operating below maximum heat flux
conditions because actual heat flux partitioning models fail to predict it accurately. Improving the
heat flux models will lead to more efficient ...
A method of fabrication of ultra-high temperature ceramic nanoparticles using acoustic cavitation
(2020-12-11)
Production of ultra-high temperature ceramics (UHTCs) has been studied for several decades, especially for applications on the aerospace industry that require materials for extreme environments. Traditional methods of ...
Ocean circulation modeling of the San Juan bay
(2013)
The Regional Ocean Modeling System has been implemented in the San Juan bay estuary, Puerto Rico, to investigate quantitatively the ocean currents at a harbor scale with tidal, wind and river forcing and to develop a ...
Generation and dynamic control of air microbubbles subjected to a complex 3D acoustic field
(2016)
The purpose of this research is to verify that the translational movement of a microbubble in a complex three-dimensional geometry subjected to a standing acoustic field, can be predicted with the acoustic pressure gradient ...
3D high-speed photography for characterization of drag and lift fluctuations of a single rising bubble
(2020-12-11)
Understanding the bubble motion in fluids is a topic of great interest in multiple applications in nature because of the significant impact and influence that this type of phenomenon has in numerous fields of engineering ...
Generation and dynamic control of air microbubbles subjected to a complex 3D acoustic field
(2016)
The purpose of this research is to verify that the translational movement of a microbubble in a complex three-dimensional geometry subjected to a standing acoustic field, can be predicted with the acoustic pressure gradient ...
Heat transfer in turbulent channel flow with roughness on the walls: numerical simulation
(2011-12)
Reynolds Average Navier Stokes (RANS) simulations are performed to study a turbulent channel flow with different roughness on the lower and upper walls. Several roughness were used. Square Bars, V-shaped and segmented ...
Using propidium iodide to determine the mechanism involved for a temporary increase in permeability of a bullfrog urinary bladder due to ultrasonically induced cavitation
(2013)
The recent advantages in medical ultrasound, in therapeutic application suggest that in the future ultrasound can be a tool for a safe drug delivery. It was found that acoustically induced cavitation permeabilizes cell ...
An acoustic method for real time air bubble detection in simulated blood vessels
(2012)
Exposure to significant changes in ambient pressure commonly occurs in divers during surfacing. These changes induce the formation of nitrogen bubbles in tissues and the presence of these bubbles can cause symptoms of ...
