Flow Characterization With Acoustic Emission Sensing, Jackson Marsh
Flow Characterization With Acoustic Emission Sensing, Jackson Marsh
Mechanical Engineering Undergraduate Honors Theses
Acoustic emissions (AE) allow for non-intrusive sensing into many types of systems. In systems where there is flow of some type, AE is very useful as these types of systems can be characterized in many ways from the collisions or creation of the flow. Correctly setting up the AE system is extremely important. Failure to do so results in imprecision and inaccurate data being collected. Because of this synchronization techniques, sensor configurations, and data acquisition systems must all align. This can be done with off-the-shelf, commercial systems, but this does not allow for customization and the ability to tailor the …
Thermal Testing And Characterization Of Nanoparticles Synthesized For Biological Treatment, Tonie Butler
Thermal Testing And Characterization Of Nanoparticles Synthesized For Biological Treatment, Tonie Butler
Mechanical Engineering Undergraduate Honors Theses
The overall goal of this research project is to synthesize iron core, silica capped nanoparticles that, when they are exposed to a particular magnetic field, will react by increasing in temperature and emitting substantial thermal output. They will be injected into the human body for biological benefit by targeted thermal radiation. Once in the human body, ideally, they will be able to target a specific area, and then a magnetic field will be applied to induce thermal output through the process of hyperthermia. As the nanoparticles emit heat, they will mimic the natural bodily behavior seen by way of hyperthermia, …
Development Of Spray Cooling For High Heat Flux Electronics, Jeremy Scott Junghans
Development Of Spray Cooling For High Heat Flux Electronics, Jeremy Scott Junghans
Graduate Theses and Dissertations
The thermal demands of modern day electronic systems require innovative thermal solutions. Spray cooling has proven to be able to cool heat fluxes orders of magnitude higher than traditional cooling methodologies. This work includes a comparison of spray cooling to standard thermal management methodologies. Key system parameters and considerations are discussed. The properties of available packaging materials and their effect on the reliability of a spray cooled system are presented. Parameters such as fluid temperature, droplet size, fluid velocity and flow rate all directly impact performance and are detailed in this work. Finally, results from of a wide range of …
