Mechanical Engineering
Skiing is a sport enjoyed by millions of people every year, yet ski boots are very uncomfortable and cost- prohibitive, resulting in a low conversion rate of first-time skiers to lifetime skiers. Additionally, Alpine Touring (AT) is seeing a surge in popularity as ski resorts become more expensive, but few companies are developing affordable products in this realm. Mad Jack Snow Sports has developed a product that they believe addresses some of the main issues associated with skiing, but they want to develop their product line further. The problem statement and scope state that the purpose of this project is …
Transient Flow Analysis Of A Closing Blowout Preventer Using Computational Fluid Dynamics (Cfd), Daniel Barreca
Transient Flow Analysis Of A Closing Blowout Preventer Using Computational Fluid Dynamics (Cfd), Daniel Barreca
LSU Master's Theses
Reliability of blowout preventers (BOPs) is crucial for drilling and production operations. Erosion of BOP components and hydrodynamic forces on rams may cause failure of BOP elements to seal the well. Transient computational fluid dynamics (CFD) simulations of fluids within the wellbore and BOP offer quantitative and qualitative data related to this reliability during the closure of various BOP components. Since limited research has been published in transient CFD simulations of closing BOPs, this thesis discusses challenges and solutions to simulating closing blowout preventers. Single component fluids are simulated through several BOP geometries such as annular preventers, pipe rams, and …
Challenges And Opportunities Of Layered Cathodes Of Linixmnyco(1-X-Y)O2 For High-Performance Lithium-Ion Batteries, Jason Frank
Challenges And Opportunities Of Layered Cathodes Of Linixmnyco(1-X-Y)O2 For High-Performance Lithium-Ion Batteries, Jason Frank
Mechanical Engineering Undergraduate Honors Theses
High energy density lithium-ion batteries (LIBs) are widely demanded for portable electronic devices and electrical vehicles. Layered-structure LiCoO2 oxide (LCO) has been the most commonly used cathode material in commercial LIBs. Compared to LCO, LiNi1-x-yMnxCoyO2 (NMC) cathodes are particularly attractive due to their reduced cost and higher capacity. Among the NMC cathodes, nickel-containing LiNi0.5Co0.3Mn0.2O2 (NMC532) is one of the most promising cathode materials undergoing intensive investigation, but suffers from a series of technical issues, such as structural instability, performance fading, and safety issues. In this …

Diseño De Un Sistema Automático Para La Aspersión De Plaguicidas En Rosas Cultivadas En Invernadero, Anderson Cifuentes Duarte
Ingeniería en Automatización
Este trabajo describe el diseño de un sistema automático, capaz de realizar la aspersión de plaguicidas en un cultivo de rosas, las cuales se encuentran en un invernadero. El desarrollo de este proyecto comienza en el sistema de aspersión, diseñando y seleccionando los componentes que cumplan con criterios de eficiencia y funcionalidad. Consecuente con ello, se conocen algunas variables necesarias para el desarrollo del sistema mecánico, analizando las diversas alternativas desde factores espaciales, tipo de materiales, factores de seguridad, entre otros. Culminada esta fase se seleccionan los sensores encargados de recibir la información del medio y trasmitirla al sistema de …

Ingeniería en Automatización
Los sistemas de diagnóstico de afasia son herramientas que le permiten al especialista reconocer el grado de afasia que posee un paciente, de esta manera facilitar y hacer más rápido el tratamiento que le permita al paciente recuperar el habla por medio de terapias, actualmente los test existentes se llevan a cabo manualmente por medio de fichas, letras, imágenes y elementos que el especialista usa para concluir un diagnóstico. De acuerdo a lo anterior se desarrollará una plataforma donde se ejecute uno de los test más usados por los expertos con pacientes afásicos, adicionalmente el médico tendrá una plataforma completa …

En el proceso de fabricación de muñecos, una de las etapas fundamentales es el relleno con fibra siliconada, que se realiza manualmente, método que presenta problemas de salud para los operarios como lo son, el túnel carpiano, artritis a largo plazo y deficiencias respiratorias, también uno de los mayores inconvenientes es el tiempo que se emplea al realizar el proceso. Para solucionar esta problemática se procede a diseñar y construir una máquina que se encarga de la separación de la fibra siliconada y el relleno de peluches, con una salida a la cual se le adaptan unas boquillas de diferentes …

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved by …

Differential Mobility Classifiers In The Non-Ideal Assembly, Thamir Alsharifi
Theses and Dissertations
The differential mobility classifier (DMC) is one of the core components in electrical mobility particle sizers for sizing sub-micrometer particles. Designing the DMC requires knowledge of the geometrical and constructional imperfection (or tolerance). Studying the effects of geometrical imperfection on the performance of the DMC is necessary to provide manufacturing tolerance and it helps to predict the performance of geometrically imperfect classifiers, as well as providing a calibration curve for the DMC. This thesis was accomplished via studying the cylindrical classifier and the parallel plate classifier. The numerical model was built using the most recent versions of COMSOL Multiphysics® …

Energy Efficiency Evaluation Of Blower Heater Non-Purge Compressed Air Dryers, Alexandra M. Botts
Graduate Theses, Dissertations, and Problem Reports
There are several compressed air dryers available for industrial use including, refrigerant, desiccant, and membrane. This research focuses on twin tower regenerative closed loop desiccant dryers, specifically: blower heater non-purge (BHNP) with and without cooling water pumps, Compressed-air Heater Purge (CHP), Blower Heater Purge (BHP), and Pressure Swing Heaterless (PSH). These styles of dryers are used mainly in industries that require extremely dry air such as, food manufacturing, medical air, or sensitive technology manufacturers. The research was conducted by collecting and analyzing real time current draw data on air compressors and associated dryers at eight different facilities (13 compressor systems) …
