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 ...
Assessment of storm-induced coastal changes on a high-energy microtidal reef-fringed coast
(2020-07-21)
This study sought to assess the storm-induced hydrodynamic and sediment transport patterns along the coast of Rincón, Puerto Rico during two storm events (Hurricane María and Winter Storm Riley). In order to assess short-term ...
Streamlined life cycle assessment of glass bottle end of life strategies in Puerto Rico
(2021-05-17)
In the following study, a streamlined life cycle assessment (SLCA) of different end-of-life strategies for repurposing or recycling glass bottles is modelled to compare the environmental impact of each strategy. This SLCA ...
Metallic phase change materials (mPCMs) stability and compatibility analysis under repetitive melting/solidification cycles
(2020-07-24)
Metallic phase change materials (mPCMs) have been demonstrated as a
potential passive cooling solution for pulse power applications. The possibility of
integrating a metallic PCM directly on top of a heat source, reducing ...
Numerical modeling of realistic atmospheric boundary layer conditions for a low-speed wind tunnel
(2020-12-11)
Atmospheric conditions occurring up to 1 km above the surface of the Earth are largely dominated by what is known as the atmospheric turbulent boundary layer. Hence, understanding the atmospheric turbulent boundary layer ...
Evaluation of methods for idea generation and selection for interdisciplinary entrepreneurial student teams
(2020-07-24)
This research explores the ideation and selection methods used by interdisciplinary student teams who use Design Thinking during the early-design stage to create solutions to real-world problems. Two experiments were created ...
Numerical assessment of roughness effects on boundary layer development over adjacent blades
(2020-06-24)
Surface roughness is a condition that affects the aerodynamic performance of compressor blades. For instance, erosion, corrosion, and fouling, among other phenomena, can cause surface roughness, in compressor blades to ...
Comparison of selected waste management scenarios for PET bottles in PR using SLCA methodology
(2021-05-14)
An increase in bottled water consumption and a failure to recover the plastic bottles at the end of their life are decreasing the capacity and useful life of sanitary landfills, having a direct impact on the environment. ...
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 ...
Transport phenomena in crossflow jets subject to very strong favorable pressure gradient
(2020-12-10)
Incompressible jets transversely issuing into a spatially-developing turbulent boundary
layer is one of the most challenging types of three dimensional flows not only due to its
fluid-dynamic complexity but also due to ...
