Central Water-Cooled Chill Water Plant
(Polytechnic University of Puerto Rico, 2015)
A medical device facility in the island
needs to determine the feasibility of replacing the
existing air-cooled chilled water system at their
main plant with a more efficient water-system in
order to reduce the electric ...
Thermal Diffusivity of a Single Crystal Silicon Wafer n-type Doped with Manganese
(Polytechnic University of Puerto Rico, 2012)
Abstract - The thermoelectric-silicon based material is gaining enormous interest since silicon is abundant and cheap. The thermoelectric materials operate in direct conversion from heat to electrical energy with no mobile ...
A Quadcopter Test Bed for Academic and Research on Control Systems Design
(Polytechnic University of Puerto Rico, 2015)
This article presents the development
of a quadcopter platform to be used for future
academic and research studies in control systems in
the Mechanical Engineering Department at the
Polytechnic University of Puerto ...
Airfoil Design Using Blade Element Momentum Theory
(Polytechnic University of Puerto Rico, 2015)
A wind turbine is a device designed to
extract kinetic energy from the wind and convert it
to mechanical energy, which in turn can be
equivalent to electric power. On this work we will
focus on the aerodynamics of wind ...
An Application of Project Management Methodology for the Development of an Advance Identity Product within Budget and On Time Delivery
(Polytechnic University of Puerto Rico, 2012)
Abstract - In an Advanced Identity Management Technology Company the purpose is to create solutions to identifying individuals in a system (such as a country, a network, or an enterprise) and controlling their access to ...
CFD Study to Analyze the Behavior of Secondary Flow Using Fillets
(Polytechnic University of Puerto Rico, 2015)
Secondary flow are a series of vortex
created at the leading edge of the blade. These
vortexes decrease the efficiency of the turbine by
creating a non-uniform flow which will pass to
successive blade stages. The ...
Aircraft Wing Spanwise Air-Load Distribution using MATLAB
(Polytechnic University of Puerto Rico, 2014)
Aircraft design is a complex task that
involves the interaction between aerodynamics,
propulsion, flight mechanics and structures. In
particular, the structural design tasks involve the
consideration of a significant ...
Preliminary Wind Turbine Assessment Using Urban Scaling Factors in Puerto Rico
(Polytechnic University of Puerto Rico, 2012)
Abstract - It is well known that wind energy applications are most effective in wide open areas. As shown in the literature, rather than completely discard the location of wind turbines in urban areas, the reduction in ...
Inviscid, Incompressible CFD Solver with Coordinate Transformation for Aerodynamic Applications
(Polytechnic University of Puerto Rico, 2016)
Fluid mechanics is a complex field of
study with many modern design applications.
Mechanical and aerospace engineers frequently
have the need to analyze fluid flow patterns for
practical design purposes ranging from a ...
Finite Element Modeling of Water Slamming on Sandwich Hull Structures
(Polytechnic University of Puerto Rico, 2017)
This article evaluates the structural
response of ship hull sandwich panels subjected to
water slamming. Structural responses were
obtained from several finite element (FE) model
simulations developed by using the ...
