All Graduate Theses, Dissertations, and Other Capstone Projects
Binder jetting technology is an additive manufacturing technology in which powder materials are binded together layer by layer forming the product from input CAD model. The process involves printing the product layer by layer, curing and sintering. The mechanical properties of 3D printed samples varies based on process parameters, hence there is a need to tune the process parameters for optimal characteristics. Three main parameters namely layer thickness, sintering time and sintering temperature were identified and the study focuses on the effect of parameters on dimensional accuracy and compressive strength of the samples. Full factorial experimental approach was used to …

Polymer composites are finding a range of applications across different fields of engineering. Hence, there is a need to understand the properties of these polymer composites. Mechanical testing can be done to determine the properties but firstly the composite must be manufactured consuming time and money. However, if the properties gained differ from those expected from composite the obtained data is rejected, and a new composite must be manufactured consuming more time and effort.
The micromechanical models play an important role in estimating the properties of the polymer composites. These models estimate the properties of the composite by estimating the …

All Graduate Theses, Dissertations, and Other Capstone Projects
This study examined consumer and professional grade handheld engines. Twenty-four consumer grade 50 hour Emissions Determination Period (EDP) trimmers and 24 professional grade 300 hour EDP backpack leaf blowers were run on four different ethanol fuel concentrations; E0, E10, E15, and E20. Six engines of each type were run on each of the fuel blends through their full EDP.
All engines were broken-in and adjusted to manufacturer specifications on E0. Then engines were emissions tested on E0 to provide a baseline and to determine the rich to lean order of the engines. Next, the leanest operating engine received E20 and …

Study Of Stability And Thermal Conductivity Of Nanoparticles In Propylene Glycol, Sumit Mahajan
All Graduate Theses, Dissertations, and Other Capstone Projects
This thesis studied the effects of gravity induced settling, thermophoresis and Brownian motion on the thermal conductivity of the Aluminum Oxide (Al2O3) nanofluids. The base fluid was propylene glycol. The effects were studied by making three samples with volumetric percentages of 0.2 %, 2% and 3% Al2O3 in propylene glycol. Sets of 22 experiments were conducted over time to understand the behavior of settling. All samples were manually mixed each time the experiment was conducted. A Thermtest Transient Plane Source TPS 500S was used to measure the thermal conductivity. Volumetric percentages and diameters of nanoparticle were chosen so that the …
