Automated Din Rail Cut And Punch Machine, Youssif Alkheder, Gaston Charreun, Derrian Flemings, Jonathan Liss
Automated Din Rail Cut And Punch Machine, Youssif Alkheder, Gaston Charreun, Derrian Flemings, Jonathan Liss
Capstone Design Expo Posters
Our project’s main goal is to optimize the process of punching and cutting DIN rail in a manufacturing setting. The current method for cutting and punching DIN rails is tedious and simply too time consuming. An operator is needed to manually load the DIN rail into the cutter, measure the required length and activate the cutter. While this simple process may not take too long at first glance, companies, like Weidmuller, must be able to produce large-quantity orders to successfully meet the demands of their customers. By turning to automation, we are effectively reducing the amount of time it takes …

Before Mars can be explored by humans, its extreme climate and environment must be investigated. This can be achieved through the deployment of weather station probes capable of measuring Martian air temperature, atmospheric pressure, relative humidity, and wind speed. The Mars Atmospheric and Climatic Survey System (MACSS) aims to collect this data, allowing predictive models of global climate patterns on Mars to be developed. These models will aid NASA in providing the needed knowledge to prepare for long-term exposure to the conditions on Mars.
The probes are compact and lightweight; they have been designed to withstand Mars’ harsh environment: extreme …

The primary purpose of this project is to demonstrate that patients can be safely immobilized using air in the general torso area so that radiation can be administered to that region. The primary target will be to treat tumors in the lungs and liver. By immobilizing patients during treatment it allows for the radiation to be consistent in targeting the desired region of the body, which would not be the case if the patient was moving. Air was chosen as the desired medium to immobilize the patient because of comfort and it provides an easy medium for radiation to travel …

Automated Source-Detector Positioner For Radiation Detection, Andre Patterson, Morgan Davis, Joel Person, Allan Roberts
Capstone Design Expo Posters
The Nuclear Engineering Department at Virginia Commonwealth University has an unmet need for an automated source detector positioner for radiation detection experiments that are carried out in lab work. During radiation data collection in radiation detection systems it is of the utmost importance that radioactive samples are positioned and moved with the highest degree of precision possible. This high degree of precision allows for more meaningful data to be collected. The current methods employed by the Nuclear Engineering Department are not as accurate as they can be due to the fact the the current detection systems are manual. Furthermore they …

Engineering design is vitally important and is the backbone of any industrial organization. The innovative approach to engineering design requires extensive calculations, estimations, workability and economic considerations to achieve a high level of customer satisfaction. Our project, for the ABB Group, was to design a structural frame-base for their transformers, and develop a set of design-standards to accommodate a range of transformer sizes. A transformer is used to step-up or step-down the voltage as needed to satisfy the electrical power needs of a facility. Industrial size transformers are an extremely heavy, sensitive and precise electrical devices that require a reliable …

NNSB tasked the Capstone team with testing the anti-condensation abilities of the Thermal Insulation Coating (TIC) Aerolon®, an aerogel-based insulation manufactured by Tnemec, using Federal test specifications for Coating Compound, Paint Antisweat. The main goal was to observe the anti-condensation abilities of the insulation and to initiate an analysis and comparison of the spray-applied aerogel insulation versus the hand-applied thick foam insulation that is currently used on ship pipes and ventilation. The plan includes creating a computer simulation of the thermal properties of the insulated cylinders as well as a physical experimental setup.
The Capstone team built an acrylic test …

The purpose of this project is to design an economical ground based weather station, with the overall goal of using these stations to gather meteorological data on the planet Mars. This data will then be used to create a working meteorological model for the planet, which in turn will be used to better coordinate the necessary resources to plan and carry out a manned mission to Mars. These weather stations will function by taking various meteorological measurements, such as air and ground temperature, wind speed, relative humidity, UV radiation levels, and air pressure, and then transmit this data to one …

The team has been tasked with designing a compact mechanism capable of deploying and retracting the Rolatube horizontally and vertically at a controlled rate in confined spaces (i.e. tank housing structures). Because workers are confined to tight quarters, a mechanism to aid in common activities is at times required. The mechanism will allow for tool deployment with attachments for easily sending tools and utilizing cameras. It will also be used to assist workers in stringing lights, keeping wires organized, and delivering hoses and tubes. This design will allow workers at Newport News Shipbuilding (NNS) to save time and energy while …
A Study Of High Temperature Heat Pipes And The Impact Of Magnetic Field On The Flow Of Liquid Metal, Udit Sharma
A Study Of High Temperature Heat Pipes And The Impact Of Magnetic Field On The Flow Of Liquid Metal, Udit Sharma
Dissertations, Master's Theses and Master's Reports
A study of high temperature heat pipe was conducted to understand its characteristics. A review of working fluid, temperature, wick structure, problems, operational limit and applications was done. Alkali metal were concluded as the most viable candidate for the working fluid.
The impact of three parameters namely magnetic field, heat flux and temperature was analyzed on the performance of HTHP (High Temperature Heat Pipe). The presence of magnetic field had the most considerable impact on reducing the pumping limit of the heat pipe while the temperature had almost negligible effect. Magnetic field results in the pressure drop and adversely affect …

Design And Analysis Of A Passive Heat Removal System For A Small Modular Reactor Using Star Ccm+, Raymond Michael Fanning
Masters Theses
"Next generation nuclear power plants, specifically small modular reactor designs, are the best alternative to fossil fuels for power generation due to their power density and low carbon emissions and constant awareness of safety concerns. A promising safety feature of new designs is the removal of heat by passive systems in accident scenarios. The passive systems require no moving parts and no intervention by personnel. These systems must be accurately simulated for better understanding of the heat transport phenomena: natural convection cooling. Due to the fact that most work developing these passive heat removal systems are proprietary information, a passive …
