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 ...
Analysis and Characterization of the Condenser of a Small Scale Solar Air Conditioning Unit
(Polytechnic University of Puerto Rico, 2012)
Abstract - This work is intended to show the characterization of a flat plate heat exchanger used as the condenser of a small scale solar air conditioning system and the recommendations for future studies. Also show flat ...
A Modified Computer Model of a Hyperbolic Energy Analyzer to Determining Its Potential for Operating as a Mass Spectrometer
(Polytechnic University of Puerto Rico, 2016)
Conventional energy analyzers are used as a plasma diagnostic tool for the determination of ion and electron energy spectra and temperature, having applications in a broad range of disciplines, including molecular spectroscopy, ...
Development of an Open Source Tool for the Preliminary Structural Design of a Small Wind Turbine Based on National and International Standards
(Polytechnic University of Puerto Rico, 2013)
Wind energy have proven to be a viable
option in the production of electricity. The benefits
from wind energy sources include reductions in
greenhouse gas emissions, water conservation and
the diversification of the ...
Parallel Plates Internal Heat Transfer Analysis for Electronic Cooling
(Polytechnic University of Puerto Rico, 2013)
Two-dimensional heat transfer analysis
using the Integral Equation Method between a
series of parallel plates with uniform surface
heating to determine the Temperature Distribution
as a Thermal Model for a Supercomputer ...

Free Convection Fresnel Lenses Concentrator
(Polytechnic University of Puerto Rico, 2013)
This project involves an evaluation of
an improved Fresnel lenses solar energy
concentrator. Its innovation consists of preventing
forced convection heat losses at the receiver area.
Heat losses by convection and by ...
Crack Growth in Compressive Stress Fields
(Polytechnic University of Puerto Rico, 2013)
To understand how to analyze
Damage Tolerance in an aerospace component
loaded in compression one must first obtain correct
Fatigue Crack Growth curves. Once the fatigue
data curves are correct one could then move
forward ...
Surface Response Modeling for Rotor-Dynamics Systems
(Polytechnic University of Puerto Rico, 2014)
This paper presents the way to
generate an equation that does not exist, to analyze
different rotor-dynamics system. With the analysis
and design software, the results desired were
obtained in order to be able to create ...
Stirling Engine Mechanism Analysis as a Function of Internal Pressure Variation
(Polytechnic University of Puerto Rico, 2014)
The Stirling heat engine was conceived
in the in the early 1800's as an alternative to the
steam engine. It is a regenerative close-cycle
engine which utilizes the expansion and contraction
of a working fluid at different ...
